OK More problems folks. I can't screenshot Crysis - which I am doing to test a possible shader regression - in the latest Git. I am using: Code: #!/bin/bash for (( c=1; c<=1000; c++ )) do scrot --delay 30 --quality 50 --thumb 58 "~/Pictures/screenshot($c).png" --exec 'rm \"$f\"' done I have also tried (in place of Scrot with appropriate switches obviously!!): Code: import All I am getting is black screenshots when the game is running (Gnome 2.30 both with Metacity and Compiz w/undirect 3D apps. switch). ATI 4650 + Catalyst 11.6 at fault?? Any suggestions?? Bob
