Stencil buffer black pixels

category: code [glöplog]
I'm getting a strange visual glitch when I enable the stencil buffer test. I get some strange black pixels, in a clearly visible pattern. When I disable the stencil test everything works like it should (other than the stencil buffer use).

Any idea on what it can be?

Eventually, you'll get some that look like Space Invaders.

it's not a genetic thing.

Maybe a message from your graphics driver in some kind of strange code?! ;)

thec: it doesn't. specially with the rest of the post processing passes.
las: maybe. I've actually solved bugs before by updating drivers.

Looks like good old video-mem Garbage/Speichermüll to me.

I had something similar when messing with shadow mapping (polygons wouldn't be correctly raterized, leading to patterns). Check your states.

Stupid gdebugger doesn't want to work. Free licence expired, and the new AMD gdebuffer sucks.

There you go, post processing for free :)

Just asking: Do you actually clear the stencil buffer and set up the correct func and ops?

New drivers solved the problem. In case you want to know.
