I'm currently running Xubuntu 14.04 (the same issues were present under Ubuntu 14.04), some of my software is just impossible to navigate and use due to display issues.
Software like Spotify, TortoiseHG, EasyMercurial, etc... Other software works fine, it's hard to pinpoint what's common about the ones that don't work.
I've tried using different display drivers, nothing helps. (Including the Nouveau drivers=
I've made no changes to what ships with Ubuntu/Xubuntu, whenever I restart the system everything is OK, but a few minutes after booting up any of these programs, the display issues come back. Closing the software and reopening it does not help either. I run a 4 monitor setup if it helps in any way.
I've been chasing the issues all over the internet, but don't know what to do any more really!
