Most of the time this happens when I click on the Launcher (left side) in unity to open a application, eg. KSysGuard.

Immediately after the click, a black screen shows up. After some time, ca. 5-10 seconds, X-Server restarts and I have to login again.
It will never happen direct after a restart of the system, usually it will take 1-10 days before this happens.

It was always direct triggered by a mouse action left click.

4k screen, 8bit, DisplayPort, 60Hz fix refresh.

heavily ppa use on this system inkl. xorg edge ppa
almost all packets are from ppa, daily updated to the latest patches.
Add software: nvidia driver & Vmware & Virtual Box & qemu, kvm
Vmware almost running all the time.

Have some limited debugging skills on Linux, but not with Xorg/nvidia, need advise how to investigate this bug.

Hi tomtom20, thanks for reporting this. It should be fixed in the next release.

Hi Aaron
appreciate the quick answer.
Sounds great. I am looking forward to this. When will the next release be available?
Would it be a good idea do switch to a beta driver for the time until the release to be able to work without fear of a segfaut.
If yes, with one can you recommend?

Please try 352.41. However, I should note that if you’re seeing this problem after several days, it implies that some application on your system is leaking memory. The fix should prevent the driver from crashing, but it will still fall back to a slower rendering path if it can’t allocate any more fast memory.
