Any possibility to test with 5.3 kernel? It seems it's fixed but not backported.
If I'm understanding it correctly, backported means it already should be in 5.4, no?
You're right, I've read it wrong.
From the reports, it seems to be compositor related. For me, kwin with OpenGL
3.1 backend works fine. xfwm4 seems to trigger the bug, maybe other compositors too.
