[ hmm, that would be a good candidate for the qxl record tool :) ]
Comment 3 Kirill Moizik 2015-03-05 10:28:05 UTC 
Similar to Bug 884753 bug reproduced on many platforms and configurations, particularly on VNC without QXL driver installed (standart VGA device) It seem like VLC bug, and it is definitely not qxl bug.
