Screen Corruption in Fedora 22

I have an issue on Fedora 22 with various Nvidia drivers, currently 352.21 with Mythtv. The first time after a reboot, using KDE, upon playing a video the screen is corrupted with diagonal lines, shapes and parts of the correct screen seen behind the corruption. This usually clears up by logging out and back in again and restarting Mythtv. This did not happen on Fedora 20. I see these errors in dmesg:

kactivitymanage[2113]: segfault at 7f1efdd3ecf0 ip 00007f1efdf86731 sp 00007fffdaef1218 error 4 in[7f1efdf72000+3f000]

and a few of these in .xsession-errors:

XcbConnection: XCB error: 3 (BadWindow), sequence: 23218, resource id: 18874376, major code: 18 (ChangeProperty), minor code: 0

Any suggestions appreciated. I have tried various display managers, and window managers, it seems hit and miss. Wayland is disabled.


Hi, can you post the basic info requested

I could not restart X with verbose logging. Let me know if the linked files are insufficient and I will try to do that later.

I do not see a way to attach a file, the last two icons above are Link and Code Block, so links to the bug report and a short video of the problem are below.
