Bug ID: 368811
Summary: Screen freezed when trying to get desktop grid from
desktop corner (3d effect)
Product: kwin
Version: 5.7.3
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: clarsonn...@free.fr
Application: kwin_x11 (5.7.3)
Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.7.2-101.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"
-- Information about the crash:
- What I was doing when the application crashed:
I was moving my mouse to the top screen to show all desktop in grid mode (3d
effect I activated)
- Unusual behavior I noticed:
The 3d effect does not occur to show desktop grid and the screen stay freezed.
My mouse is still moving around the screen and I can do a Ctrl-Alt-F2 to see on
tty what is wrong.
The kwin process is then consuming 100% CPU and at some time, that can be
really long, crashed.
Frequency:
It is quite frequent but it not always.
To workaround this issue:
I move to a tty (Ctrl-Alt-F2 for example)
then I start a new DISPLAY=:0 kwin --replace & and the desktop restart to work
properly.
Sometimes, I need to re-activate the desktop 3d feature. (Shift-Ctrl-F12 twice)
At this point everything is back working.
The freezed kwin process is still there, running and I let it like this. And
some point, this process, randomly timed, crashed.
I'm using the nvidia driver (not nouveau)
$ rpm -qa *nvidia*
kmod-nvidia-4.6.6-200.fc23.x86_64-367.44-1.fc23.x86_64
