Created attachment 112831 [details] Krashreport from KDE Working with KMail is nearly impossible, because KMail crashes when changing folder, jumping to next message, creating mail. Sorry for not specifying better - crashing evry 10-30 klicks in KMail - doesnt matter where to klick
These crashes are caused by the nouveau OpenGL drivers not able to handle the multithreaded contexts QtWebEngine uses. There are patches for Qt to fall back to software OpenGL when detecting this buggy combination. Please report this issue to the bug tracker of your distribution asking to apply these patches.
