I noticed another strange thing with pipe-video on my rv670.
Until recently there was a bug that made the mesa demo lodbias misrender.
It's fixed now in master and pipe-video, but if I use pipe-video + vdpau
decode (xvmc untested) then lodbias reverts to the broken state.
I don't install pipe-video, so just using libvdpau_g3dvl makes my
installed (master) driver behave differently on that test. I have to
reboot to get working lodbias and have failed to regress it any other way.
Sounds like some register bits for LOD biasing didn't get set correctly.
So they are programmed once by the vdpau driver and never gets resetted
to their initial state. Which piglit test exactly shows a regression?
shouldn't be to hard to reproduce and fix.
fbo-generatemipmap shows it.
