Description Yann Vernier 2004-12-12 06:21:09 UTC 
When scissoring is enabled, glClear() fills the wrong region. I think I've
tracked down the problem, the URL points to a patch.

Hi!

I'm doing a huge rewrite of via_ioctl.c as part of bug 1950. Among other things,
I'm abstracting the blit operations so that bugs like this should get less likely.
Hopefully that rewrite will fix this problem as well.

Could you check if the latest CVS fixes this?

Yes, the viaBlit unification in via_ioctl.c solved this.

Mass version move, cvs -> git
