Summary: 3d rendering artifacts ("r128" X11 driver on ATI Rage
128)
Product: openSUSE 10.2
Version: Final
Platform: i686
OS/Version: openSUSE 10.2
Status: NEW
Severity: Normal
Priority: P5 - None
Component: X.Org
AssignedTo: sndirsch@novell.com

Found By: Customer
Using X11 (r128) on SuSE 10.2 (Pentium 4, 1.6GHz), both 2D and most 3D graphics
work well.
But some OpenGL 3D programs show 3D rendering artifacts: additional triangles
that should not be visible. Problematic software includes Google Earth (as
soon as a line path is on display) and various 3D screen savers.
With several OpenGL 3D screen savers (including "Rubik's cube", "Pipes 2",
"Moebius", "Ant with headlights", "Superquadrics"), artifact triangles appear,
mostly between the 3D object and the screen's left side.
I could provide screen shots if it helps.
