--- Comment #10 from Daniel Neugebauer <daniel.neugeba...@gmx.de> ---
When I run X-Plane I use a wrapper script to disable and reenable compositing
via dbus for better rendering performance. Since installing X-Plane 12 in
September 2022 I noticed I also have a high chance to experience this issue
when the application exits and I repeat that several times via my wrapper
script (about once every 5 to 25 times, very sporadic). The issue is still
present with kwin and Plasma workspace 5.25.5.
The screen turns mostly black. The Konsole terminal window I use to run the
script gets duplicated and flipped vertically. Only the non-flipped copy has
window translucency applied (I can see the desktop background image). Contents
may or may not be completely visible. The image on screen is stable as long as
I don't move the mouse or interact with any windows. When moving the mouse
across the screen, parts (widgets?) of the windows currently hovered by the
mouse cursor appear shortly but flicker/disappear as the mouse get moved
further. The parent widget hierarchy seems to appear at random (partial window
repaints?). Other desktops (I use a total of 8) did not seem to be affected in
the corruption I encountered today (I don't remember if I checked that before).
Memtest86 has been run several times since I noticed these issues and
MemtestG80 (for VRAM) has also been executed two times so far without any
errors being detected. MCE log entries do not correlate to screen corruption.
I can confirm that disabling the compositor helps. Reenabling does not resolve
the issue, a restart is required to fix it.
The commands used to toggle the compositor from my script are:
qdbus org.kde.KWin /Compositor suspend
qdbus org.kde.KWin /Compositor resume
There are no entries in system logs (metalog, I don't use systemd) related to
kwin or otherwise correlating to the corruption.
Looking back at my package installation history since October (not sure if I
already encountered it in September as well), the problem has been observed
using:
- Gentoo Linux
- proprietary Nvidia drivers 515.65.01, 525.60.11 and 525.60.13
- X.org X11 server 21.1.4
- Mesa 22.1.7 and 22.2.3
- Qt 5.15.5 and 5.15.7
- kwin 5.25.5
- Plasma workspace 5.25.5
Hardware:
- NVIDIA GeForce GTX 1070 (ASUS GeForce GTX 1070 STRIX O8G Gaming, 8192 MB
GDDR5)
- Intel i7-4790K @ 4.0GHz (4 cores x 2 HT)
- 32 GB RAM
