Comment 5 for bug 1319220

I have some good news. I discovered a few days ago that the bug is gone for me.
The bad news is that I have no idea what 'fixed' it since I have made quite a few changes during the past few days. The biggest was getting the proprietary ati driver instead of the open alternative but I seriously doubt this has anything to do with the bug. One of the things I messed with as well was the theme of my desktop (theme as such + icons).

I'll try and see if I can reverse the changes I've made and will report should I find something. As for the theme & icons, this doesn't seem to be the thing but you may try just in case.

I'm not sure whether cpu usage was high when I suffered from the bug. I should have noticed but who knows.
