I spent some time digging around on the xbmc linux forum and I dug up the exact issue that I am having in Boxee with the ATI 1250 (AMD 690G chipset) - they call it "ghost flurry image".
It looks exactly like this:
And - they have a fix for it! See the third post on this page by XBMC developer "elupus" on 06/10/08.
He's working on this file:
file: xbmc\cores\VideoRenderers\VideoShaders\YUVRGBShade r.cpp
Any chance Team Boxee can have a look at the above thread and advise?? Is this something that I can try to implement in Boxee or does it need to be implemented by developers in the build package somehow?
Thanks in advance!
