Hi
After upgrading to windows 7 x64 and using EVR as renderer (overlay mixer isn't an option anymore) I see the entire bottom black bar being gray and part of the right top bar.
Self explanatory screencap:

The partial gray top bar isn't always here between computer reboot, the bottom one is ALWAYS here.
Using any decoder (ffdshow alone, coreAVC alone) in any color output (RBG32, YUV...) with any resolution (SD, HD720p/1080p)
There is a temporary solution to the problem: pressing "5" on the numpad (pan-scan reset), everything turn out black, but getting out from fullscreen and getting back to fullscreen gets the problem back
I previously seen the problem on XP using VMR7, but a bit differently (player element was painting gray where they were moved)
I see those bar clearly since I perform a YUV->RBG32 conversion that move the correct luma of 16-235 to 0-255 (gray to back and white)
Other maybe useful info:
GC: Ati Radeon X1650
Display: Samsung 20" 1600x1200 DVI
OS: Fresh windows 7 x64
Preferred decoder: coreAVC->ffdshow->upscale/RBG32conversion->vsfilter
Thank you for reading.
