Graphic glitches with Catalyst 10.9 (HD4650) and some games

[Myloch]

Hi guys. I'll post my problem here with the hope I'm not the only one with this problem.

In the beginning I thought my videocard got burned (like what already happened in the past) but after 10 minutes of 0 artefacts using ati tray tools I'm a bit more relaxed.

This happens with some (usually old games): the image flickers, just like old image frames only partially disappeared, and some squares appear on the screen. I suspect it's a catalyst bug. Please post your experiences.

Edit: I don't think it's overheating because my card got pretty low temps and the games are not gpu intensive.
