OK then. I would blame bypass but based on comment #5 you're effectively
saying bypass is not the problem (because it still happens with bypass
disabled).
Other changes that landed between those two package versions (r1028..1033) are
relatively insignificant. So the possibilities are:
1. One of those insignificant changes has caused the problem; or
2. You made a mistake when trying the workaround from bug 1218735; or
3. You downgraded some other package which has fixed the problem.
I think #3 is now most likely, so... Using the "working" packages,
please run "ps auxw | grep mir" and verify for us that Mir is in fact
running. Also try "ps auxw | grep unity-system-compositor".
Please also try generating a full package list for both the working and
non-working states, with:
dpkg -l > working.txt
and then break it again before doing:
dpkg -l > nonworking.txt
and attach those.

[radeon] Graphic glitches and screen corruption (vertical lines) on

Bug description:
Since the latest Ubuntu Mir update which enabled the bypass support I
get heavy graphic glitches when using the unity-system-compositor. I
had to disable it in order to use the desktop as the graphic glitches
made it impossible to read anything.
Before this update everything worked fine.
