<pre>My TV Tuner is displaying some odd "glitches"; little bits of the screen that
seem to be corrupt. Some form of memory corruption or other. Its not just
tearing. The link below has some pictures, but I can make some more if you
like. Also, (this is very weird), the problem will go away if I slam my CPUs
with extra work to do. The easiest way to do this is run Handbrake and let it
encode a video. Luckily this takes awhile on my slow CPU, but to watch TV, I
have to keep restarting a handbrake job for the video output to be readable.
I originally thought this was a tvtime bug, and then a v4l bug, but it goes
away if I install the ATI/AMD binary (fglrx) drivers. However, that isn't a
good option for me since getting those drivers to work with recent kernels and
gnome 3.16 is nearly impossible. Since the fglrx drivers doesn't have the
problem, I will assume its a driver issue.
My older bug report to tvtime with the pictures is here:
<a href="https://sourceforge.net/p/tvtime/bugs/747/">https://sourceforge.net/p/tvtime/bugs/747/</a>
Any chance there is some magic configuration to fix it?
