I recently encountered an extreme video flickering problem whenever I try and use full-screen mode. Presently I am using the latest release (8.10 Atlantis) of XBMC under Windows 7, AMD 5050e processor, onboard ATI 3200 HD using HDMI out.
Background:
I originally installed XBMC under different hardware on Windows XP about 3 months ago (don't know the build, sorry). Sadly, it didn't run due to OpenGL issues. Later, I ripped out the motherboard, dropped in a new Foxconn A7GM-S board and processor, then installed Windows 7, keeping the old install of XBMC. I started XBMC and everything worked great. Fullscreen and all.
At some point, I opted to install the latest build of XBMC because I thought maybe it was the reason for the black borders around my screen. Things haven't been the same since. I had also reinstalled Windows 7 and the latest ATI Catalyst Control Center. Now it seems that no matter what I do, I cannot stop the seizure-inducing flicker of full-screen mode in XBMC.
I noticed something interesting however: If XBMC is in the background (tabbed out to another application), the flickering stops and it goes up to the 60 Hz rate when viewing the info screen. The moment I tab back to XBMC it drops dramatically, somewhere around 15 Hz and varies a bit.
My guess is that there is some sort of problem with vertical sync. I have it set to always enabled and my display is a 47" Olevia 247FHD-T11, 1920 x 1080 @ 60 Hz.
I've tried reinstalling several other builds that I could find, which seemed to date back as far as early January, but nothing worked.
Has anyone else experienced anything similar? I've searched for past posts and found a lot of people onboard Intel graphics blaming Intel drivers and such, but there seems to be conflicting information. Some say it worked fine under Beta 2. In my case it isn't Intel, but rather ATI/AMD. Due to the fact that it did indeed work for a short time under Windows 7, I can't blame the OS and I believe it was the same graphics driver.
Suggestions greatly appreciated, and I'll gladly report back any testing that is requested.
Thanks!
