--- Comment #1 from junjun...@gmail.com --- Created attachment 160982 --> https://bugs.kde.org/attachment.cgi?id=160982&action=edit New crash information added by DrKonqi okular (23.04.3) using Qt 5.15.10 I was wondering if this crash happens without a running google chrome. Without running any other applications (including chrome) except Okular, the crash happend again. So my conclusion is that Okular alone crashes immediately after the laptop goes to sleep. -- Backtrace (Reduced): #6 0x00007f79b370fa42 in QXcbBackingStoreImage::put(unsigned int, QRegion const&, QPoint const&) () from /lib64/libQt5XcbQpa.so.5 #7 0x00007f79b37103d2 in QXcbBackingStore::flush(QWindow*, QRegion const&, QPoint const&) () from /lib64/libQt5XcbQpa.so.5 #8 0x00007f79c5904e66 in QBackingStore::flush(QRegion const&, QWindow*, QPoint const&) () from /lib64/libQt5Gui.so.5 #9 0x00007f79c5fbcd4d in QWidgetRepaintManager::flush(QWidget*, QRegion const&, QPlatformTextureList*) () from /lib64/libQt5Widgets.so.5 #10 0x00007f79c5fbe938 in QWidgetRepaintManager::flush() () from /lib64/libQt5Widgets.so.5 -- You are receiving this mail because: You are the assignee for the bug.
