--- Comment #1 from Oleksandr Bezushko <insiderser+...@protonmail.com> --- Created attachment 147556 --> https://bugs.kde.org/attachment.cgi?id=147556&action=edit New crash information added by DrKonqi kwin_x11 (5.24.3) using Qt 5.15.3 - What I was doing when the application crashed: Just trying to switch windows using Alt+Tab. I've noticed that the more windows are open, the higher chance of crash there is. -- Backtrace (Reduced): #12 0x00007ffb4608ed48 in KWin::WindowThumbnailItem::updateOffscreenTexture() (this=0x5594577e29a0) at /usr/src/debug/kwin-5.24.3/src/scripting/thumbnailitem.cpp:432 #13 0x00007ffb44720463 in QtPrivate::QSlotObjectBase::call(QObject*, void**) (a=0x7ffc5762f670, r=<optimized out>, this=0x5594571e5360, this=<optimized out>, r=<optimized out>, a=<optimized out>) at ../../include/QtCore/../../src/corelib/kernel/qobjectdefs_impl.h:398 #14 doActivate<false>(QObject*, int, void**) (sender=0x559455f45040, signal_index=3, argv=0x7ffc5762f670) at kernel/qobject.cpp:3886 #15 0x00007ffb460663a6 in KWin::Scene::paintScreen(QRegion const&, QRegion const&, QRegion*, QRegion*, KWin::RenderLoop*, QMatrix4x4 const&) (this=0x559455f45040, damage=<optimized out>, repaint=..., updateRegion=0x7ffc5762f810, validRegion=0x7ffc5762f808, renderLoop=<optimized out>, projection=...) at /usr/src/debug/kwin-5.24.3/src/scene.cpp:282 #16 0x00007ffb4612c2e7 in KWin::SceneOpenGL::paint(KWin::AbstractOutput*, QRegion const&, QList<KWin::Toplevel*> const&, KWin::RenderLoop*) (this=0x559455f45040, output=0x0, damage=..., toplevels=<optimized out>, renderLoop=0x559455d56b40) at /usr/src/debug/kwin-5.24.3/src/scenes/opengl/scene_opengl.cpp:259 -- You are receiving this mail because: You are watching all bug changes.
