-- Information about the crash:
Everytime I lock my desktop and come back to it (5 minutes later is enough), I
have like 20 "Discover has crashed" notifications in my system tray. This
mostly happens when locking the system but also sometimes while using it even
though it seems to be more rare.
The crash can be reproduced every time.
