Application: plasmashell (6.0.2) Qt Version: 6.6.2 Frameworks Version: 6.0.0 Operating System: Linux 6.8.1-300.fc40.x86_64 x86_64 Windowing System: Wayland Distribution: "Fedora Linux 40 (KDE Plasma Prerelease)" DrKonqi: 6.0.2 [CoredumpBackend] -- Information about the crash: I logged into Plasma 6.0.2 on Wayland in a Fedora 40 KDE Plasma installation. I was troubleshooting a kwalletd6 crash when starting the Proton VPN GUI which I reported at https://bugs.kde.org/show_bug.cgi?id=482819 The problem involved qca 2.3.8. I built qca 2.3.8 with a patch by Albert Astals Cid https://bugs.kde.org/show_bug.cgi?id=482819#c11 I upgraded to the qca 2.3.8 build with the patch. I logged out of Plasma and logged in again. I ran the following steps described by Albert to run kwalletd6 under valgrind then run the Proton VPN GUI to reproduce the crash https://bugs.kde.org/show_bug.cgi?id=482819#c9 "Open a terminal Start kwalletmanager5 and press the close wallet button (force if needed) killall kwalletd6 (run it twice to make sure it has not re-spawned itself) valgrind kwalletd6 Now in another terminal kwalletmanager5 and press the open open wallet button protonvpn-app" The panel disappeared and reappeared automatically right after I ran protonvpn-app in Konsole. A plasmashell crash notification was shown. plasmashell crashed in dri2_invalidate_drawable in the radeonsi driver in mesa 24.0.0. The argument dPriv was null in dri2_invalidate_drawable which might've led to the crash. The crashing line ../src/gallium/frontends/dri/dri2.c:99 was drawable->lastStamp++; in the following static void dri2_invalidate_drawable(__DRIdrawable *dPriv) { struct dri_drawable *drawable = dri_drawable(dPriv); drawable->lastStamp++; This problem didn't happen before when I ran the Proton VPN GUI. The reporter is unsure if this crash is reproducible. -- Backtrace (Reduced): #5 dri2_invalidate_drawable (dPriv=0x0) at ../src/gallium/frontends/dri/dri2.c:99 #6 0x00007f5e25d54127 in QtWaylandClient::QWaylandEglWindow::updateSurface (this=0x562892e60320, create=false) at /usr/include/qt6/QtCore/qpoint.h:129 #7 0x00007f5e2b63c2a9 in QWindow::resize (this=0x7f5e114230f0, newSize=...) at /usr/src/debug/qt6-qtbase-6.6.2-6.fc40.x86_64/src/gui/kernel/qwindow.cpp:1995 #8 0x00007f5e2de2ee1b in PlasmaQuick::DialogPrivate::syncToMainItemSize() () at /lib64/libPlasmaQuick.so.6 #9 0x00007f5e2adf2a24 in doActivate<false> (sender=0x7f5e10e7d8c0, signal_index=25, argv=0x7ffe29b8b1c8) at /usr/src/debug/qt6-qtbase-6.6.2-6.fc40.x86_64/src/corelib/kernel/qobject.cpp:4051 Reported using DrKonqi
