Update:

* It seems this is not related to mesa vs gallium, as it both happens when
using r600c or r600g.
* If I turn off Option "Composite" (set it to "Disabled"), then the corruption
does not appear.

I've found this similar bug,
https://bugs.freedesktop.org/show_bug.cgi?id=27529, but there the issue is more
severe.
