    Ubuntu 14.04 + AMD Catalyst 14.3 Beta - Screen distortion.

    Hello everyone.

    I have an Acer Aspire 7552g notebook with an AMD Radeon 6650M video card. The problem is when laptop puts display to sleep (due to AFK for some minutes) it then resumes to distorted screen (not always but 1 from 4 resumes is with distortion). I had same issue with Ubuntu 13.10 too, also I have tried several driver versions from Catalyst 13.11 betas to 14.3 beta, all with this same problem.

    Does anyone had same problems? Is there any workaround?

    P.S.: I can not use open-source drivers, I need OpenGL 4.2+ to do my job.

    P.P.S.: here is a screenshot:
