Controller (rev 02)
During normal use, doing things that I do many times each day, I started my IDE
(Phpstorm) while running Firefox, Chrome, Thunderbird and Konsole.
A Youtube video was playing in Chrome.
Instead of the first small IDE window, the Plasma Desktop panels disappeared
together with all the window decorations (borders menus etc...).
A big greyish window was left behind, with pieces of other windows showing
around it.
Any attempt to switch between running applications failed.
Hitting Ctrl-Alt-Backspace twice did reset X11.
Virtual consoles were working, so I used init 3 and then init 5 to restart all
the processes.
In both cases, after login, the plasma desktop reappeared, but not the window
decorations.
I had to reboot to get the system back to normal.
When I looked at the journal, I saw:
Jun 24 18:47:19 bigboy kernel: [drm] stuck on render ring
Jun 24 18:47:19 bigboy kernel: [drm] GPU HANG: ecode 0:0x9f47f9fd, in chrome

Jun 24 18:47:19 bigboy kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
