There are no significant error messages in the logfile. The first
thing to check (if you leave the system on 24/7) is whether you have
adequate cooling, especially for the video card. I'd also suggest
running memtest86+ to check your system memory.

Do you see the same screen corruption if you leave the system running
with mythfrontend closed (i.e. leaving the system at your chosen
desktop)?
