Description Motor 2000-12-08 12:09:06 UTC
Machine: Intel Celeron 333 192mb RAM, Matrox g200 8Mb SDRAM.

Previously this machine was running RH6.2 using the UTAX GLX project to
provide excellent quality 3d acceleration with Quake 3.

After a fresh install of RH7.0 and Xfree4 everything is still running ok
(speed is fine, agp is enabled and so on), except that there are now a
large number of small "tears" where the polygons making up a room in Q3
join up - almost as if they do not fit together properly, and bits of the
background are showing though.

I'm assuming that this is a bug in the mga DRI driver supplied with
XFree4.0.1, but I have been unable to find any reference to it elsewhere.

Comment 1 Mike A. Harris 2001-03-17 20:06:29 UTC
You're probably right.  Can you try out the latest XFree86 4.0.2a-2 and
Mesa 3.4-12 packages from:


Let me know if they work better for you.  You'll also need the rawhide kernel.

Comment 2 Mike A. Harris 2001-08-25 07:50:29 UTC
The latest XFree86 4.1.0 in rawhide has dramatically improved 3D
