I have observed the case a bit more. When machine is coming out of hibernation - the opensuse boot screen experiences corruption: 1/4 of the screen is drawn correct - the rest contains garbage. The pattern is pretty same - the screen is cut by four triangles with basements along the sides.
Important thing I noticed - the screen recovers itself after some time. Although font damage in gnome-shell is permanent, refreshing parts of the screen with some content has some chance to make it work as it should. THEN it stays correct. Also, I suspect that initial four triangle show right after login, is gnome 3 trying to blend-in, by applying a four-triangle surface filled with black and then increasing the alpha. The moment alpha is all way up, gnome removes them. With this bug - it looks like triangle flash which then suddenly correct. To sum up, I am totally sure this is about texture memory transfer within OpenGL context, I am nearly sure it happens because the texture memory IS NOT CLEARED when its asked or the content is overwritten when stored, or the memory is not protected from being overwritten by garbage. However, the system is fully stable even when I used it with 1GiB constantly swapping.

There is a memory corruption issue that affects users of the rs690m, to varying degrees. For many most people, it makes the desktop unusable. Workaround: *Note: This is a workaround, not a fix. It will give you a usable system. [Natty]: Regression: This workaround now only provides 2d/software rendering, and one must either: * Choose choose the "Ubuntu Classic" session from the GDM Login screen or * Install the "unity-2d" package. [code] sudo su echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf exit [/code] Note that this doesn't totally fix the issue, but brings your desktop to a workable state. Freedesktop.org has dealt with one bug having to do with graphics corruption on the rs690m. That bug has been fixed, but the issue of graphics corruption in general has not been resolved. A new bug has been opened with freedesktop.org to continue pushing through the resolution of this issue.
