Description Stephen Davis 2004-07-15 14:50:04 UTC
epsxe, quake3, xmms opengl spectrum analyzer and zsnes open a window or go
fullscreen but the window remains blank although the program seems to run,
glxgears draws panning red lines from the top left corner of its window, and
tuxracer draws white and brown lines from the top-left corner for the terrain
and falling snowflakes in title. Some objects - the distant background, trees,
the start line - are drawn correctly - but the menu text and heads-up display in
the game do not appear at all.

The programs seem to run fine in all other respects, and generate no error
messages or warnings of any kind. 'dmesg' output and Xorg.0.log show nothing.

The problems happen regardless of resolution or bit depth, windowed at any size
or fullscreen. The only workaround is to turn off DRI and use software rendering.

I believe this is fixed in X.Org CVS.  Please update and try again, or use the
binary snapshots from http://dri.sf.net/ (which should be the same code, SiS-wise).

Yes, the drivers in
http://www.freedesktop.org/~dri/snapshots/sis-20040718-linux.i386.tar.bz2 work
fine. Thanks.
