Clear pin fullscreen

i’m trying to use the good old pseudo motion blur like demonstrated in tonfilm’s motionblur patch. i used this effect quite often but now i encounter a weird problem. the renderer seems not to turn off clear when being in fullscreen.

in windowed mode, everything looks like it should be but in fullscreen the clear seems to be set to 1 again. the same happens with tonfilms motion blur patch. toggle the clear pin with a key command didn’t help.

any ideas ?

seconds later…don’t cry for help if you don’t look at all the options…

i was messing with the graphicscard settings…me fault :)
