Comment 134 for bug 888039

Hi everybody,

Daniel, I have your used your unity PPA for some time now (+/- 2 weeks).

My first impression was that it solved the problem, but after some hours the bug just returned.

Window movement gets very slow after using unity for some time (some hours max). When it occurs I can see all windows stopping to refresh until I stop moving the window. This is most visible if I play a video in one window and try to move this window (or any other window) at the same time.

The moment I stop moving the window the video refreshes and plays again and the window moves to the new position. During all the time, the sound of the video continues normally.

If I use the 2D version of unity or XFCE, LXDE everything works normal. It also "works" if I move the window very slowly. I can see some refreshes while moving the window but the video stutters.

There are a lot of bugs out there reporting "bad performance" of unity in Ubuntu 11.10, so it is difficult to decide which is the right bug report.

Right now, I do not know which possible solution to try next. From what I saw this far this bug report matched my problem the most but unfortunately it did not solve the problem.

Does anyone have suggestions for the next step?

Thanks!
