I see corruptions when minimizing, maximizing and using desktop effects

[Tommy_CZ]

Hi, I installed fglrx driver and every time I use some effect of kwin, it shows me small corruption, like when I push alt+f2 to invoke krunner, for few seconds, I have something wierd with stripes, before krunner shows itself.
Probably due to fglrx, please contact it's developers, I'll do the same and post here an URL.

I noticed this behaviour since xorg-server got upgraded from 1.9.x (on multiple distributions)

Tommy_CZ, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg-server REPLACE-WITH-BUG-NUMBER

Please note, given you already have done this in a prior release, performing this on a release prior to Trusty would not be helpful.

Thank you for your understanding.
