@Jacek Pawlyta 1. Does the crash occur after system upgrade (especially graphics drivers upgrade)? Or doing something else with graphics drivers (switching GPU maybe?) 2. If the crash occurs, what do you have to do to have a working KRunner again? Just start KRunner again? Reboot the computer? 3. When the crash occurs again, could you immediately run this in Konsole: $ killall -9 krunner $ krunner And check if the crash repeats? If it does repeat, try this: $ killall -9 krunner $ QT_QUICK_BACKEND=software krunner Does this fix the crash and allows KRunner to start properly? @Nate Graham >Frameworks Version: 5.75.0 So this is still before https://invent.kde.org/frameworks/kdeclarative/-/merge_requests/37 was applied.
Created attachment 134191 [details] gl-create.py 4. When the crash occurs, please run the attached gl-create.py Python script and tell us what the output was: QOpenGLContext::create() == ???
