This is so weird because I don't think this was happening the first weekend after installing Mavericks, but in the last few days, my XBMC is playing 1080p videos I'm streaming all messed up. There are odd red lines and glitches in the video that do not go away. 720P seems to work fine, and even some 1080p works but I'd say 75%+ of all 1080p videos are doing this now. I'm wondering if it has happened since me messing with Airplay as a 2nd display (not mirrored) to my Apple TV3 or the HDMI video output I've connected/disconnected several times. Rebooting, reinstalling XBMC, you name it, nothing now is seeming to get rid of these playback issues. Has anyone else ran into this? Hoping there is some sort of workaround as it is driving me nuts!
