error log
SUMMARY
kwin will consistently spam
kwin_scene_opengl: 0x2: GL_INVALID_OPERATION in glDrawBuffers(unsupported
buffer GL_BACK_LEFT)
errors when i press alt-tab and hold alt so the preview box appears and i start
selecting different windows with the arrow keys by pressing the tab key again.
It only seems to happen when the previews are activated because just a quick
single alt-tab so that the last window gets raised immediate and no previews
are shown doesn't trigger the error.
As far as i can tell no functionality is missing though because the previews
are working.
STEPS TO REPRODUCE
1. enter the alt-tab preview box
2. use arrow keys to select different windows
3. hold the selection for a few seconds.
OBSERVED RESULT
kwin spams GL error messages
EXPECTED RESULT
no error messages
