Mac OS X Fullscreen MKV playback flickering green

Hi

I have a strange problem.
I have OSX 10.7.4 , and XBMC run w/o problems with all files....
Until I downloaded a nightly (4/6 i think), which messed up the fullscreen playback of MKV files.
When I try to play a MKV file, the entire screen is flickering in green and magenta vertical lines, but if I go bak to the menu (with the movie still playing in the background, the movie plays w/o flickering (but very choppy)
All other media is unaffected.

I tried to go back to 11.0 stable, but everytime I try to open XBMC, it crashes.

Any help would be appreciated....

looks like you have a lib scan going on at the same time.

Could that be the reason for the strange flickering?

Hmm, tried to turn off hardware acceleration, and the flickering stopped...
Strange...

do a mediainfo on the video content that flickers green with hardware acceleration on, there's something about its format that VDA does not like.

Sample (50MB)

But actually every single MKV file I have played on the nightlies respond in the same way...

I had the same green flickering issues on my Mid 2011 MacBookPro until i turned off hardware acceleration, but worked fine on a 2011 Mac Mini,

I have been using the June 18th build from here http://xbmc.picmania.org/index.php?dir=osx%2F but now going back to 2012-04-03_XBMC_opdenkamp_xvdr.dmg48876KB Apr 03 2012 12:56:39 PM since i was having some odd Audio issues passing DTS / AC3 and mpg via the optical out on the mini.

There seems to be some issue with AMD GPUs and hardware decoding related to a change in rendering. Unfortunately, all my OSX boxes have Nvidia GPUs and I cannot investigate/fix until I get my hands on something with an AMD GPU in it.
