Bad rendering of software icons

I'm absolutely unsure of the product & components where this belongs, so it's highly likely it's not to the right place, if so I'm sorry.

I'm not a regular KDE/Plasma user, but still use it sometimes here and there. I can't remember the last time I used it, but it's highly likely it was on 5.x, and the issue I report here is a regression; it wasn't there back then.

SUMMARY

Many icons renders incorrectly. This happens in the application launcher, the bottom panel, the task switcher on both X11 and Wayland, and also in the window decorations when they exist, but only for Wayland: icons for window decorations (at least for those I checked) renders correctly on X11.

Most of those I noticed this seems to be base GNOME icons where a black background appears when there shouldn't be one. But the worst I could see where on Fractal and Alacritty icon which probably is the worst of all.

STEPS TO REPRODUCE
1. Just run KDE/Plasma with some of the affected programs installed.
2. 
3. 

OBSERVED RESULT

Icons rendered incorrectly.

EXPECTED RESULT

Icons should be correctly rendered.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: ArchLinux
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.2.5
Qt Version: 6.8.1

ADDITIONAL INFORMATION

See joined screenshot for an example of how these two icons appears. If needs be I can add later on a screenshot of how it should appears taken from another DE, but checking their respective website could give an idea.

Additionally, I also have a different issue with Thunderbird icon, only on task switcher and in the application launcher in the Windows section if it runs: instead of the icon it shows a generic Wayland icon, but I think this is a quite different issue that should be reported elsewhere?
Comment 1 Porkepix 2025-01-24 15:36:32 UTC
Maybe unrelated, but messages I could find in `journalctl`:

Massive number of these:
```
janv. 24 16:26:42 T470-clement kwin_wayland[8791]: kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT)
```

```
janv. 24 16:19:31 T470-clement kwin_wayland[8791]: kwin_core: Cannot grant a token to KWin::ClientConnection(0x6092d77eea10)
```

I have a whole lot of other warnings appearing in logs related to KDE/Plasma, but it feels unlikely for it to be related to this issue.
Comment 2 Porkepix 2025-01-24 16:05:27 UTC
Additional note: Alacritty's icon renders correctly (little bit blurry, but it's not the only one and I assume it's because of missing icons sizes) in the task switcher only in X11.
