Or kwin doesn't work correctly. What can be the problem then if it's not kwin?

So, can anything be done about it? Can you please collaborate with AMD
developers on this somehow?
This IS a bug, because in practice, the session doesn't recover. If the reason
lies in the radeonsi bugs, then they have

The bottom line is, for the end user this is not working as it should.

> There is no indication of this being a kwin bug at this time.
According to AMD developers, KWin is likely not using OpenGL robustness
extensions correctly, since GPU reset should be supported properly in the
kernel

The current status of this ticket is ambiguous.
Comment 1 says that resets should be handled gracefully in kwin. If they are
not, this ticket should get reopened.

I can try triggering GPU reset explicitly for a test to see how kwin reacts.

OK, just got another hang and reset. Desktop became garbled, with some
reactions to input.
I switched to tty, and run:
DISPLAY=:0 kwin_x11 --replace
That started, and showed various OpenGL info about the system in the

Oh, I missed one preceding dmesg part:

OK, it happened again, and I can tell it was a reset, since I see it in dmesg
(see below).
The session got corrupted again, but was reacting on some garbled fashion to
input like before.

It reacted in as something was happening on the screen due to Alt+F2, but it
was garbled.

Thanks, I'll give it a try.

Also, when reset happens, there is a brief period when everything is completely
frozen, and then it starts reacting on input again, and this what happened
here.
It even reacted on me opening krunner with Alt+F2, but all
