I'm new to this forum, so I don't know how to attach a log file. I tried entering the text in this message, but it said it contained too many characters (62262 > 60000). I'm using Windows 8.1 x64, VLC 2.2.1, AMD R9 270X GPU (14.12 drivers).
The first file I played experienced no colour sync issues initially. I hit the skip next button, and the next file had the colour sync issues. I stopped the playback and restarted the second file, the colour sync issue disappeared. I hit the skip previous button, and it played the first file again, this time it did have colour sync issues. The Modules Tree tab didn't mention any video output module, just libvlc -> playlist -> [interface qt4, interface win32, interface hotkeys, audio output directsound].
I disabled the hardware YUV -> RGB conversion option, and was unable to reproduce the colour sync issues.
Edit: I've just reproduced on the integrated Intel graphics on my i5 3570k. Since Evasii0n has seen it on two NVIDIA cards and I've seen it on both my Intel and AMD chips, I think it's safe to say we can rule out graphics driver issues and that the common denominator is the way VLC is calling the hardware YUV -> RGB conversion acceleration.
