Arch KDE window is extremely small

[Quackdoc]

Running from terminal crashes the terminal, running from gdb shows that the app is running. but no window is visible.

EDIT: Window is extremely small when it opens

Are you on Wayland?

[Quackdoc]

That is correct

[Ax9D]

That might have to do with winit, the windowing library i'm using, which is known to have buggy support for Wayland.
As a workaround, you can force it to use XWayland by setting the environment variable:
WINIT_UNIX_BACKEND=x11

rust-windowing/winit#305

Actually, It turns out the window does open, I had the same issue doing what you said, it turns out it is opening a window that is 3x8 pixels on a 4k display, it happens in x11 too. when I close and open the app same thing

I've changed the issue to better reflect what is happening

Alacritty is affected by the same problem so it's either a winit or plasma issue. I started running into it after a recent plasma update. You can work around it by right-clicking the application in the panel and choosing Resize, then just move the cursor until you have a usable size and click to finish resizing.

Other than that the Wayland backend has worked fine for me so far.

This has been worked around in Plasma 2.23.4. A proper fix is already in winit 0.26.0, but the PR to use that in egui (emilk/egui#930) has not landed yet at the time of writing.

[Ax9D]

I have updated to egui 0.16.0 which includes this fix

[Quackdoc]

only tested briefly but it works fine for me
