Status changed to 'Confirmed' because the bug affects multiple users.

Doing unity --reset solved my issues with flickering - but after doing that I realized that I may have lost some useful information for debugging.
Anyway, I have played a little with unity options in ccsm during 12.04 testing, so my unity configuration was certainly not stock and the problem could have been totally my fault.

I did not play with Unity options and I have the same problem on my HP Pavilion dm1 netbook since the update to Unity 5.8: flickering screen. Very unpleasant, not usable.

But unity --reset seems to help indeed.
