Bug ID: 449270
Summary: Crash in QXcbScreen::surfaceFormatFor() after
QXcbGlxIntegration::createPlatformOpenGLContext)
Product: kwin
Version: 5.23.4
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: szots...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.23.4)
Qt Version: 5.15.2
Frameworks Version: 5.89.0
Operating System: Linux 5.15.12-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.4 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
I pressed Alt+Tab when KWin crashed.
Similar crash happens after I change monitor inputs and then I start KRunner or
click on a taskbar icon. I'll try to gather more backtraces from those
occasions.
KDE Qt version:
libqt5-qtbase-devel: 5.15.2+kde268
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
