HTML5 export for Godot 4.x takes 1-2 minutes to load on macOS #70691

Luzzotica · 2022-12-29T01:18:56Z

Bugsquad note: This issue has been confirmed several times already. No need to confirm it further.
Bugsquad note2: Also, please avoid asking when this will be fixed. The issue is confirmed to be with the version of ANGLE used by Chromium, so we are all waiting for Google to ship the fix.

Godot version

4.0.beta10

System information

MacOS Monterey 12.2.1

Issue description

Godot games block the main thread (And potentially crashes it) on MacOS.

Untested for Windows or Linux.

This happens from both a generic build and when you run the project in a browser from the engine.

Steps to reproduce

Create a new project for Godot Beta 10.

Add a UI Button to the screen.

Have it print things out, whatever you wish.

Add an HTML5 export, install the HTML5 export library if necessary.

Click the run on HTML5 button on the top right.

Proceed to wait for 1-2 minutes before the game will fully load.

Minimal reproduction project

@Calinou I feel like this isn't the same as those. I don't believe it's a size issue.

Running locally on MacOS on both Brave and Chrome: Took about ~2 minutes and 30 seconds for the game to load. Both Brave and Chrome wanted to kill the tab. It had locked up the entire browser for (Couldn't go to any other tab).

Running this on Windows, and the game loads in ~10 seconds.

If this is a size issue, then MacOS Chrome and Brave are just INSANELY slow to load things. Which doesn't seem right.
Also, since I'm running it locally, I assume the web assembly can load faster... This might be untrue, but I doubt that it is.

Zireael07 · 2022-12-29T18:45:55Z

In that case, it might be shader loading and/or conversion (correct me if I'm wrong, but MacOS converts stuff to ANGLE behind the scenes, doesn't it?)

In that case, it might be shader loading and/or conversion (correct me if I'm wrong, but MacOS converts stuff to ANGLE behind the scenes, doesn't it?)

I also think may be a shader compilation issue. Chrome definitely uses ANGLE, but I am not sure about Brave. macOS doesn't use ANGLE when running on desktop though.

While attempting to fix the gl_compatibility renderer on macOS I experimented with using ANGLE, but found that the shader compilation times ended up increasing by over 100X. In #70065 I was able to speed up shader compilation times and get gl_compatibility working on macOS without ANGLE. However, since chrome uses ANGLE, my guess is we are hitting those pathological shader compilation issues anyway. I am not sure what exactly in the shader is causing the issue (it may even be a bug in ANGLE).

The issue of Chrome crashing on MacOS 13 does indeed exist, and Firefox takes over 2 minutes to load.

I'm completely new to C++ dev, but I would like to help with this issue.
What can I do to help?

Luzzotica · 2023-02-21T05:14:55Z

Can confirm, 4.0 RC2 is still taking minutes to load on Brave on MacOS.. Causes my entire browser to lock down completely.

dhnm · 2023-02-27T15:42:22Z

The issue still persists in rc4, rc5, rc6. In Forward+, Mobile, and Compability mode. Chrome hangs, Firefox takes a while but loads, and Safari has a infinitely loading spinner and reports the following in the console:

Thanks @mgc8, all this is great support for all the suffering mac Godot users like me

mgc8 · 2023-09-09T19:51:44Z

I'm not sure why it disappeared, but I can confirm that the Chrome flags suggestion posted earlier works great in Chrome 116.0.5845.179/macOS/M1, and is an easier temporary workaround rather than the Terminal version of the same (at least until the Chrome devs make Metal the default):

leafo · 2023-10-05T20:37:39Z

So, for now, the "open iframe in its own tab/window" option remains as a workaround

On itchio, you should assume that at some point your game will be required to be loaded in an iframe that has been generated by itch.io. A solution that involves breaking out the frame is not a long term fix because we have system in place to automatically inject site locking to prevent shady third-party platforms from embedding our games to steal bandwidth.

while itch.io could improve the situation by adding a bit of browser-detection code to switch between 'credentialless' and 'request-corp' as needed

Unfortunately require-corp has a bunch of side effects with regards to any external references on the page, and may impact how the site operates, so the solution isn't simply change the value of the header. This is why we opted for credentialless since it's mostly transparent solution, but the browser compatibility is not ideal.

I think our long term fix (assuming safari never supports the header) will probably involve launching the game in a separate page containing only an iframe and different headers specific to safari, instead of trying to execute the game on the full project page.

Edit: Was double checking the code and it looks like this was already implemented for the Game Embed tool located in the uploader's dashboard. If they generate an embed URL from there, it will provide a link to the game that will use require-corp instead of credentialless. Example game URL: https://itch.io/embed-upload/8831158?color=1e0e11 (note url may not work in the future if this particular developer removes their game)

Edit2: I deployed a fix that will cause Safari to always load games in a new window using the embed URL I described above that uses the require-corp header value. Should resolve any issues for Safari users, at the expense of slightly different user experience.

transmutrix · 2023-10-05T22:48:04Z

On Newgrounds, SharedArrayBuffer support works in Safari as well as the other major browsers (tested with the same build of the same project, etc.). I'm not sure which method they've used, however, or if it would translate easily to itch, if it would be useful to look into, or who over there to ask about it if it would be useful.

Edit: I should note my test wasn't with a Godot game, but a plain jane Emscripten build of a C program—the underlying issue appears to be the same.

Hi @leafo, thank you for dropping by! This looks like a good, pragmatic solution given the current state of browsers, with every major one seemingly having a different, incompatible issue related to this. I can confirm that the "new window" works nicely for itch.io games in Safari, so at least that's solved now for end-users. Hopefully the browser developers will also move on with updates/fixes to make the whole process less frustrating for both site owners and game devs (three months later, Chrome still hasn't switched to Metal as default back-end on macOS)...

transmutrix · 2023-10-07T19:55:20Z

The "new window" solution works great on desktop! On mobile, it gives me a 404 error in the new tab (tried iOS and iPadOS, both Safari and Chrome, but did not try Android).

kamko0 · 2023-11-08T23:58:41Z

As of right now me using IOS doesn't seem to load my game that used Godot4, so even with the Embed game link it doesn't work.
Not sure if there will be a fix anytime soon but at least it works on pc for now.

revanj · 2023-11-20T22:08:47Z

Hi there @leafo , thank you so much for the fix and for creating the website indie devs know and love!

In recent exports, the new window in safari appears to give 404. This seems to indicate that the generation of the embed link is not working correctly. Is there anything users can do to specify the embed link, or otherwise make the new window use the correct embed link? This is on a laptop M1 Mac.

Maybe on Chrome, but now it takes forever on Firefox/macOS.

nickarora · 2024-03-26T16:06:36Z

As an update, it does appear that Chrome is now using the Metal renderer by default now. I am using Chome 123.0.6312.59 and I have verified that the Angle Metal renderer is being used. I have not changed any flags or set a custom profile.

Also the "image rendering issue" renders without issue.
https://arturitoproductions.itch.io/testingimageissue (password: godot)

I also use Brave but it still not updated to use the Angle Metal Renderer. I suspect its only a matter of time for the other browsers to follow suit.

Thank you very much for updating us! I suspect firefox and brave should update soon to match, but I worry that safari is still a long ways off. At any rate, having everything work well on the others puts us in a much better position.

That demo locks up my Chrome, but no longer locks up my computer.

It will sit there like this for a long time:

Interesting that this appears to be a CPU bound issue, why is that?

nickarora · 2024-03-27T06:31:49Z

@tavurth The screenshot you posted indicates you need to relaunch Chrome for chrome version you've listed to take effect. I might try relaunching chrome and trying again. The other difference is that I am using an ARM (M1) machine, but I can't see why that would matter.

Once you've restarted Chrome, can you open the console and run the following commands and share the output:

const gl = document.createElement("canvas").getContext("webgl");
const debugInfo = gl.getExtension('WEBGL_debug_renderer_info');
gl.getParameter(debugInfo.UNMASKED_RENDERER_WEBGL);

FWIW, on my machine, I see:

ANGLE (Apple, ANGLE Metal Renderer: Apple M1 Pro, Unspecified Version)

chrissearle · 2024-03-27T06:38:05Z

That's interesting. Can I ask what chrome version?

Looks like its M* related though - I have what chrome says is latest as of today: 123.0.6312.87 on an intel macbook pro and a M3 macbook pro and I get:

Intel: ANGLE (ATI Technologies Inc., AMD Radeon Pro 5300M OpenGL Engine, OpenGL 4.1)

M3: ANGLE (Apple, ANGLE Metal Renderer: Apple M3 Max, Unspecified Version)

starry-abyss · 2024-03-27T11:10:30Z

On my M1 laptop the build with a few number labels from here https://arturitoproductions.itch.io/testingimageissue opens quickly on Chrome, but slowly on Firefox. And on Safari it's popping up a new itch.io window, which gives a 404 error :)

nickarora · 2024-03-27T15:00:46Z

Firefox has likely not adopted the Angle Metal renderer as their default yet.

It may be the same with the latest version of non-ARM Chrome installs. If the x86 (intel based) installs of chrome are not yet defaulted to Angle Metal renderer, then we'll have to wait a bit longer for Godot 4 web exports to work as expected for all mac users. As of today, it should be working for M1, M2, M3 mac users with the latest version of chrome

I believe the Safari 404 issue is unrelated (there's some discussion above about a missing required header on itch.io)

tavurth · 2024-03-27T15:03:17Z

The screenshot you posted indicates you need to relaunch Chrome for chrome version you've listed to take effect

Yep, was just keeping the version the same as you listed in your original post. Now it's:

And the result of the GPU probe:

'ANGLE (Intel Inc., Intel(R) Iris(TM) Plus Graphics 655, OpenGL 4.1)'

nickarora · 2024-03-27T15:17:01Z

It appears the new chrome default has only been applied to ARM based macs. intel based macs may have to wait a bit longer. Still, it's promising that these changes are slowly trickling out

starry-abyss · 2024-09-02T10:55:28Z

I believe this is fixed when using the new Godot 4.3 no-threads export.
