I'm using Ubuntu 12.04 on my PC (i5 core; 8gb; gtx 560) and found some weird glitches. First, when I drag qmmp window, it moves kinda spurting Second, when I scroll through my bookmarks in firefox, selection moves slow too. Here is the video I recorded to show these things http://www.youtube.com/watch?v=wd0G0en1LYk What's the problem? Thanks.
