graphic intel problem ghosting

[DelSol]

i think when i use an opengl or graphic accelerated software (ie watching a movie, or looking at the opengl screensavers) when i move the window then the picture will start to ghost. i have an intel mainboard dq963fx with an gma3000 and the device manager identifies my graphic as a 82Q963/Q965 Integrated Graphics Controller. please look at the screenshots i took. also when i disable hardware acceleration (one of my nes emulators allowed me to do that) this problem did not occur.

thanks in advance!
