Bug ID: 468415
Summary: plasmashell crashed when interacting with the
Application Launcher menu icon with radeonsi and
amdgpu errors
Classification: Plasma
Product: plasmashell
Version: 5.27.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: matt.fagn...@bell.net
Target Milestone: 1.0
SUMMARY
I was using Plasma 5.27.4 on Wayland in a Fedora 38 KDE Plasma installation. I
used Firefox 114.0a1 20230411215906 on Wayland and closed it. The Firefox crash
reporter appeared due to a crash like that reported at
https://bugzilla.mozilla.org/show_bug.cgi?id=1826583 I clicked Quit Firefox
with the report checkbox enabled. I moved the mouse cursor to the bottom-left
of the screen over the Application Launcher menu icon, and I was going to click
on it. The menu didn't appear. plasmashell crashed, and the screen went black.
Plasma restarted automatically. The journal at the time of the crash showed
plasmashell errors like plasmashell[1443]: EE
../src/gallium/drivers/radeonsi/si_state_shaders.cpp:2557
si_build_shader_variant - Failed to build shader variant (type=4) and
plasmashell[1443]: amdgpu: The CS has been rejected (-9), but the context isn't
robust. These errors involve the radeonsi mesa 23.0.1 driver and amdgpu 6.2.10
kernel driver. Given the error plasmashell[1443]: LLVM failed to upload shader,
LLVM might be involved. llvm 16.0.0 is installed.

plasmashell crashed when I moved the cursor over the Application Launcher menu
icon and was going to select it shortly after that. The same type of amdgpu
error was shown, but not the radeonsi one.

drkonqi failed to start and no crash was shown by coredumpctl so I don't have a
trace. This type of crash doesn't normally happen when interacting with the
Application Launcher menu. The problem might involve a race condition.
STEPS TO REPRODUCE
1. Boot a Fedora 38 KDE Plasma installation updated to 2023-4-11 with the
updates-testing repo enabled. The system might need to have an AMD GPU using
the radeonsi mesa driver and amdgpu kernel driver given the errors.
2. Log in to Plasma on Wayland
3. Move the cursor over the Application Launcher menu icon at the bottom-left
of the screen
4. Click on the Application Launcher menu icon at the bottom-left of the screen
5. If plasmashell didn't crash, repeat 3-4 until it does.
OBSERVED RESULT
plasmashell crashed when interacting with the Application Launcher menu icon
with radeonsi and amdgpu errors
EXPECTED RESULT
plasmashell wouldn't crash
