--- Comment #4 from kot...@hotmail.com --- Created attachment 143632 --> https://bugs.kde.org/attachment.cgi?id=143632&action=edit New crash information added by DrKonqi kwin_x11 (5.23.3) using Qt 5.15.3 - What I was doing when the application crashed: Multi-monitor setup. Resume from suspend with 2nd monitor only. Display goes inactive after 15 mins. Wake display, access task menu, crash. - Custom settings of the application: OpenGL 3.1, low latency Sorry if this isn't helpful but I've had this crash across multiple major version updates now; it is most definitely persistent. -- Backtrace (Reduced): #4 0x00007f5ce7460331 in QXcbVirtualDesktop::surfaceFormatFor (this=0x0, format=...) at qxcbobject.h:53 #5 0x00007f5ce74609d6 in QXcbScreen::surfaceFormatFor (this=this@entry=0x5591ed6ae6c0, format=...) at qxcbscreen.cpp:653 #6 0x00007f5ce65e2d00 in QXcbGlxIntegration::createPlatformOpenGLContext (this=<optimized out>, context=0x5591ed8d1c20) at qxcbglxintegration.cpp:196 #7 0x00007f5ce7458a88 in QXcbIntegration::createPlatformOpenGLContext (this=<optimized out>, context=0x5591ed8d1c20) at qxcbintegration.cpp:282 #8 0x00007f5cee7f4ef1 in QOpenGLContext::create (this=0x5591ed8d1c20) at ../../include/QtGui/5.15.3/QtGui/private/../../../../../src/gui/kernel/qguiapplication_p.h:110 -- You are receiving this mail because: You are watching all bug changes.
