I also had to add blender to the application list in for NVidia card and disable AA completely. Not only red black issue but also selection was weird.
Hi,
i got the same problem too.
Now I just checked my NVidia Card settings to your recommended settings, but it didn’t work vor my Laptop:( (Asus, i5, Win7 - 64Bit, 4GB RAM, NVidia GT325M - using Blender-2.49-Win64).
But then i went again into the Graphiccard settings again and made following
settings:
"3D-settings-management-> Program Settings->
- add Blender.exe to program list
- use NVidia Highperformance Processor
- Anti-Aliasing Settings -> select: application dependend"
And all of a sudden the issue was gone.
But all please note, this solution referrs to NVidia Graphiccards.
Hope it works for many of you too:)
I gotta be the odd man out here. I had this “red ghosts” glitch with an nvidia card under WinXP when I enabled AA on the card – makes for better-looking playblasts, for one thing. But it was never more than a momentary thing, never had any affect on any functionality so I ignored it.
Having now switched to Vista with an old ATI card w/legacy Catalyst drivers installed, even with card AA enabled, no glitch at all, in fact Blender is running smoother and faster than I could have believed,* just screams for me both in the UI and when rendering. So much faster n the UI that I actually have to relearn some of my editing technique, I’m over-correcting for my former machine’s slowness.
Point is, I think this glitch is extremely machine-specific, and as such, probably has little to do with Blender’s guts.
*EDIT: Except for sculpting, much to my chagrin. Big probs in Sculpt mode with the ATI card, remedied to some degree but not 100% satisfactory.
FWIW in my experience the quickest way to cause this glitch with nVidia cards is to play a DX-8 game. Something funky happens when you shut down (assuming you are running DX-9 or DX-10).
