[mythtv-users] Fedora 22 Screen Corruption

[Mark Goldberg]

I have an issue on Fedora 22 with various Nvidia drivers, currently
352.21 with Mythtv 0.27.4 from Rpmfusion. The first time after a
reboot, using KDE, upon playing a recording, 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 libQt5Sql.so.5.5.0[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.

Here is a short video of what I see.

I am using VDPAU on a GTX750. I have also gotten occasional lockups of
Myth frontend while playing a recording, requiring a restart of the
Myth front end.

Any suggestions are welcome.
