FWIW this only happens with [QtQuickRenderSettings] SceneGraphBackend=vulkan in ~/.config/kdeglobals The Vulkan backend is experimental, so I'm afraid you're in "there be dragons" territory. |
SUMMARY I see an occasional crash in KWin; so far I haven't found a way to reproduce it reliably, it seems to happen most often while using Alt+Tab to switch between konsole and chromium. STEPS TO REPRODUCE 1. Use Alt+Tab to switch between konsole and chromium a number of times, seems to happen at random. Probably can also happen with other applications; so far I've never observed it unless chromium was running, but that may just be random OBSERVED RESULT Stack trace of thread 87579: #0 0x00007ff20009ea1c __pthread_kill_implementation (libc.so.6 + 0x93a1c) #1 0x00007ff20004a412 raise (libc.so.6 + 0x3f412) #2 0x00007ff203d4e132 _ZN6KCrash19defaultCrashHandlerEi (libKF6Crash.so.6 + 0x8132) #3 0x00007ff20004a4c0 __restore_rt (libc.so.6 + 0x3f4c0) #4 0x00007ff20009ea1c __pthread_kill_implementation (libc.so.6 + 0x93a1c) #5 0x00007ff20004a412 raise (libc.so.6 + 0x3f412) #6 0x00007ff2000334b0 abort (libc.so.6 + 0x284b0) #7 0x00007ff2000333d8 __assert_fail_base.cold (libc.so.6 + 0x283d8) #8 0x00007ff200042de2 __assert_fail (libc.so.6 + 0x37de2) #9 0x00007ff203d35433 epoxy_get_core_proc_address (libepoxy.so.0 + 0x12c433) #10 0x00007ff203d284d5 epoxy_glWaitSync_global_rewrite_ptr (libepoxy.so.0 + 0x11f4d5) #11 0x00007ff2039067db _ZN4KWin19WindowThumbnailItem15updatePaintNodeEP7QSGNodePN10QQuickItem19UpdatePaintNodeDataE (libkwin.so.6 + 0x5067db) #12 0x00007ff202ff4dfa _ZN19QQuickWindowPrivate15updateDirtyNodeEP10QQuickItem (libQt6Quick.so.6 + 0x3f4dfa) #13 0x00007ff202ff3497 _ZN19QQuickWindowPrivate16updateDirtyNodesEv (libQt6Quick.so.6 + 0x3f3497) #14 0x00007ff202ff313e _ZN19QQuickWindowPrivate14syncSceneGraphEv (libQt6Quick.so.6 + 0x3f313e) #15 0x00007ff2031da95c _ZN15QSGRenderThread3runEv (libQt6Quick.so.6 + 0x5da95c) #16 0x00007ff200b2192e _ZN14QThreadPrivate5startEPv (libQt6Core.so.6 + 0x52192e) #17 0x00007ff20009ccd1 start_thread (libc.so.6 + 0x91cd1) #18 0x00007ff20011b588 __clone3 (libc.so.6 + 0x110588) EXPECTED RESULT Doesn't crash SOFTWARE/OS VERSIONS Linux/KDE Plasma: OpenMandriva Cooker, kernel 6.10.6, glibc 2.40 KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION Mesa 24.2.0 (also observed earlier with 24.1.5), AMD GPU (radeonsi, polaris12) epoxy 1.5.10 running on xorg (not (x)wayland)
