@mrfab: You're not using orm=backbuffer (as per this bug) if you're using orm=pbuffer (as per your post)...
Difference for me with new settings backbuffer -pbuffer Backbuffer enableas thin squares all ower map area ,so pbuffer seems to be an better option.
I posted here because i had the same bug before updating to latest ati driver so again this bug no longer appers for me fglrx driver 10.10
