Bug ID: 506356
Summary: plasmashell randomly freezing while using system
Classification: Plasma
Product: plasmashell
Version First 6.4.1
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
Application: plasmashell (6.4.1)
ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.15.0
Operating System: Linux 6.12.35-1-lts x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 6.4.1 [CoredumpBackend]
-- Information about the crash:
I was reading visual novel 'Fate/stay night REMASTERED'
https://store.steampowered.com/app/2396980/Fatestay_night_REMASTERED/ and then
my plasmashell instance froze up completely. I tried to restart it with
'systemctl restart --user plasma-plasmashell', and systemd did kill it, but it
never came back up even though it said the service was running. I had to
'loginctl terminate-user' myself to break out of this, and then DrKonqi came up
helpfully informing me that plasmashell had segfaulted.
I have done fairly in-depth reverse-engineering on Fate/stay night REMASTERED
and can provide the information that this game uses OpenGL 4 to render its
graphics. The game is also running through Proton as the developers do not
provide a native Linux build.
When this happens, my Discord also starts freezing up and flashing, almost as
if it's lost GPU context for hardware-acceleration.
I use Plasma on X11 (believe me I'd use Wayland if I could). Read F/SN by the
way.
The crash does not seem to be reproducible.
