Dear Maintainer, this issue was also discussed upstream in [1] [2].
There the reason was given, that running the application inside a KDE plasma session makes Qt pick up some KDE shared libraries (KDEPlasmaPlatformTheme.so), which does its own GL interactions, which is not expected by qrenderdoc at that time. A package built with upstream patch [3] makes qrenderdoc not crash at startup inside a KDE plasma session. Kind regards, Bernhard [1] https://github.com/baldurk/renderdoc/issues/2772 [2] https://github.com/baldurk/renderdoc/issues/2752 [3] https://github.com/baldurk/renderdoc/commit/101dbda8c34888bf2051c3c257da3a1702705ef9 (rr) bt #0 0x00007f1d2b62cfd2 in glGetString_renderdoc_hooked (name=eGL_VERSION) at ./renderdoc/driver/gl/gl_hooks.cpp:158 #1 glGetString (name=eGL_VERSION) at ./renderdoc/driver/gl/gl_hooks.cpp:158 #2 0x00007f1d285f4359 in getGlString (param=7938) at ./src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp:144 #3 updateFormatFromContext (format=...) at ./src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp:174 #4 0x00007f1d285f5b7e in QGLXContext::init (this=0x56133bffce60, screen=<optimized out>, share=<optimized out>) at ./src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp:416 #5 0x00007f1d285f31b7 in QXcbGlxIntegration::createPlatformOpenGLContext (this=<optimized out>, context=0x7ffebfee1400) at ./src/plugins/platforms/xcb/gl_integrations/xcb_glx/qxcbglxintegration.cpp:197 #6 0x00007f1d2a3827bd in QOpenGLContext::create (this=this@entry=0x7ffebfee1400) at kernel/qopenglcontext.cpp:612 #7 0x00007f1d2513603c in checkBackend (checkContext=...) at ./src/platformtheme/qtquickrenderersettings.cpp:43 #8 initializeRendererSessions () at ./src/platformtheme/qtquickrenderersettings.cpp:79 #9 initializeRendererSessions () at ./src/platformtheme/qtquickrenderersettings.cpp:52 #10 0x00007f1d29cb7aaf in qt_call_pre_routines () at kernel/qcoreapplication.cpp:317 #11 QCoreApplicationPrivate::init (this=this@entry=0x56133be84620) at kernel/qcoreapplication.cpp:849 #12 0x00007f1d2a337b8c in QGuiApplicationPrivate::init (this=this@entry=0x56133be84620) at kernel/qguiapplication.cpp:1530 #13 0x00007f1d2ab684c9 in QApplicationPrivate::init (this=0x56133be84620) at kernel/qapplication.cpp:513 #14 0x000056133a722884 in main () (rr) https://invent.kde.org/plasma/plasma-integration/-/blob/97a2a802948d7ff91be6db564472d2c82286bd2f/src/platformtheme/qtquickrenderersettings.cpp#L103 https://github.com/qt/qtbase/blob/ca254a0937d58e573a0e2b210590de2a02326e5f/src/corelib/kernel/qcoreapplication.cpp#L291
