Description Nicholas Miell 2004-07-31 17:41:42 UTC 
Attached is a screenshot from the game Neverball. The ball shouldn't have any
circular bands.

This doesn't happen very often, although it seems to occur regularly on level 12
of the easy set. (The ball will flicker between correct and wrong regularly
throughtout the level.)

I've also seen it in other apps, so it doesn't appear to be a problem with
Neverball.

The ball is rendered correctly with LIBGL_ALWAYS_INDIRECT.

BTW, this is with an ATI FireGL 8800, Xorg 6.7.0 (xorg-x11-6.7.0-5), on FC2/AMD64.

Can no longer reproduce with a recent Xorg CVS snapshot
