Do you get any warnings about uniforms in your journal? This sounds like an issue I already fixed

Comment 2 kodatarule 2024-02-26 21:39:20 UTC

I see this, if it applies
"kwin_wayland[1061]: kwin_scene_opengl: 0x502: GL_INVALID_OPERATION error generated. Uniform must be a matrix type in call to UniformMatrix*."

Okay, cool, that should already be fixed. If you still see it on 6.0.0 anyways, just reopen this
