Pixel artifacts and corruption plus system freeze and instabilities with the free radeon driver (AMD HD 6570)

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).
