There are changes in the 3.13 kernel that make Radeon HD 7xxx hardware faster and more stable. Ubuntu 14.04 "Trusty Tahr" currently has the 3.13.0-12.32 kernel. Are you able to test it?
Also, the upstream 3.14-rc4 kernel has this commit (which has also been ccd to the stable kernel series) which eliminates the display corruption some people have had with recent kernels: author Alex Deucher committer Alex Deucher commit 6d8ea7de3f5035610f3bfacbe35e7b71ad1e4663 tree 215fe5cacbd723866e8515ae41734d56dc547bd6 parent 78b035101999d8d071781778c019c387dc8bebb2 drm/radeon: fix display tiling setup on SI Apply the same logic as CI to SI for setting up the display tiling parameters. The num banks may vary per tiling index just like CI.

Before this, I was running 12.04 64bit without any graphic driver related problems. I tried both Catalyst versions from official repository, latest 13.12 drivers from AMD site and open source drivers (radeon), and I can't tell which one was more unstable. After a few hours of use, I could not play any videos with any of the drivers (tried mplayer and VLC, both crashed with various errors), OpenGL isn't working anymore (even glxgears was crashing) and I had various artifacts on screen (like parts of window rendered on the wrong place on screen). Putting machine to sleep and waking it up later produced even more errors. I also tried to turn off various things in CCSM, without any positive results. Steam client had terrible flickering almost all the time, it was practically unusable; also about 8 of 10 times it was crashing on startup. After about two weeks of trying to make it usable, I gave up and installed MATE desktop. Not a single graphic error since then. Steam works flawlessly, 3D games also, Wine games, playing videos, everything. I kind of like how Unity works, I was using it for the last two years as my main desktop (on the same machine), but this behaviour is unexpected and utterly undesireable.
