Description bastimeyer123 2024-07-20 14:50:27 UTC

SUMMARY
When showing the task switcher (thumbnail grid - not sure if relevant), kwin_wayland logs the following errors every time, while the second one is spammed massively while the task switcher stays opened when holding the Alt key.
```
Jul 20 16:46:57 basti-pc kwin_wayland[51611]: This plugin does not support raise()
Jul 20 16:46:57 basti-pc kwin_wayland[51611]: kwin_scene_opengl: 0x3: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT)
```

STEPS TO REPRODUCE
1. Have task switcher with thumbnail grid set up
2. Have multiple windows open
3. Press (and hold) its key binding (Alt+Tab)
