[mythtv-users] video artefacts

[Eyal Lebedinsky]

For a while, since I replaced my video card (now a GEFORCE GT 710), I notice artefacts from one
workspace leaking to another. Here is a short example where the news playing on one desktop is
showing through a static image on another. I think it is showing in the black areas.

I replaced the card once but I still see this problem.
- is it the card?
- or the driver?
- or X?
- maybe the machine(the mobo) itself?

I decided to start asking on the mythtv list, but may need to shift to linux-media
or fedora users list...

TIA

This is fedora 28 up-to-date.

There was talk of issues with the driver but not with this latest 396.45.
