Hi! I got a garbaged screen since a big xorg update about 3 weeks agoon F20. I usually don't complain as problems tend to get fixed very fast. Though this one didn't and I decided to upgrade to F21...to notice the problem is there too. I haven't found any recent bug describing the issue and was therefore posting here wondering if it was me or not. A bit more information about this issue: - "effect" visible at http://snag.gy/AGPaq.jpg - lpci -v bash-4.3$ lspci -v 00:00.0 Host bridge: Advanced Micro Devices, Inc.
