I tested resetting to 1, now instead of "artefacts" my screen freezes and shakes... I know now exactly where this is reproductible. For example, in "area 22" map, start with Strogg (soldier), you will land on the right of the Strogg base, then just turn left (looking to the Cyclope), and there is artefact (or now freeze&shake). I noted that watching the Cyclope on this map always results in this behavior.
The patch has been merged to master now, so this bug can be closed.
As for the artefacts, it's probably better to open a new bug so this could be tracked separately. I have tried earlier versions of r600g and as far as I can tell this is not a regression.
