VST interface is cropped at the right

[TheChocolateOre]

I opened a VST (with VeSTige) and it rendered fine. But, navigating its UI (after Show/hide GUI), sometimes it gets bigger to accommodate its content.
And that's the problem, it gets cropped at the right.

I'm suspecting that LMMS expects that the VST GUI size is contant. So, it renders a viewport with that constant size.
When, the VST changes in size, that viewport stays the same, resulting in a cropped UI.
Turns out, the VST has functionality inside the cropped area, that can't be used, as it is out of reach.

No, resizing the window that contains the VST doesn't work. The viewport inside that window is the problem.

The viewport must scale aswell. Not, all VSTs have a constant content size.

Example of a VST we can test with?

[TheChocolateOre]

Steinberg LoFi Piano
Basically, it runs inside their HALion Sonic SE 3
So, when you open the latter in LMMS and click the top EDIT tab, it navigates to the LoFi Piano UI, which turns out to be
bigger than the HALion's initial size.

I've also faced this issue with VSTs from https://quietmusic.eu/
I own the Love-fi VST and while this issue does not happen with the lite version, it happens with the paid version. Lite version is version 1.1 while paid is 1.3.
This issue also happens with their newly released QM Sounds VST. See screencap below: UI is cropped and stays that way even if I resize the window. These VSTs all load properly in FL Studio.

Can you select "No embedding" under the VST plugins embedding setting (found in the performance tab of the settings) and see if the issue still occurs?

@Spekular
Using "No embedding" seems to do the trick, thanks a lot!
I also tried using Halion Sonic SE with the Steinberg LoFi VST. The issue is also fixed using this method.

Glad you got this working! I think this is a duplicate of #4087, so I'll close this one.
