Created attachment 96797 [details] Screenshot Hello, Each time I tried to use the free radeon drivers with my desktop computer, I got those corrupted pixels when X starts. The issue effects increase as the session time grows: more and more artifacts, more and more character alterations (for instance, Thunderbird is displaying blocks instead of characters), more and more instabilities (programs ends up by a segmentation fault, and could eventually lead to a system freeze). Otherwise, Gnome Shell starts without error. `glxgears` works and returns good FPS. And the virtual consoles remain safe & clean; switching between them and X has no effect. The system was stable, without screen corruption when I used the AMD’s FGLRX drivers. How could I fix this issue? Any idea? This ticket seems quite similar, should I try the proposed patch? <https://bugs.freedesktop.org/show_bug.cgi?id=66932> Chipset: AMD Radeon HD 6570 (Turks family) with 512MB dedicated RAM (AFAIR). CPU: Intel DualCore E6300 with 4GB RAM. Kernel: Linux 3.13-1-amd64. And I use the defaut Xorg configuration (i.e. no configuration files).
