[mythtv-users] Myth 0.22 / VDPAU / Horizontal "noise/sparkles"

[Pete Ratzlaff]

When I was playing with overclocking my 9400M, I noticed when the gpu
temps started rising that I would start seeing sporadic image corruption
similar to what you've seen. So it's a long shot, but do you have any
reason to suspect temperatures in the chassis have risen lately? Perhaps
a case fan has stopped working or something? Well it's just an idea. You
can check on the temp with

  nvidia-settings -q GPUCoreTemp

and anything above, oh I don't know, maybe 70-80C at normal clock
settings might be cause for concern.
