Description Yuri Timenkov 2025-11-20 12:48:41 UTC 
Application: konsole (25.08.3)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.0
Frameworks Version: 6.20.0
Operating System: Linux 6.17.7-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 6.5.2 [CoredumpBackend]

-- Information about the crash:
Hard to tell what exactly leads to the crash. IIRC Most of the times konsole was in the background, once lockscreen  was on, otherwise another window / desktop focused.

I run AMD APU with Wayland.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault


warning: Can't open file /memfd:wayland-shm (deleted) during file-backed mapping note processing
