where B means that black pixels are displayed always.


I don't know what is the problem exactly but the attached patch removes this bug. (May cause new ones, too...)

Could you try the attached instead? This one also fixes a few other problems I noticed.

The problem is solved if I use the patch.

Running the xtest 4.0.11 the following tests are failed using 4.4.99.903+patched s3 driver, using 1024x768 8bpp:

XListPixmapFormats
XDrawArc
XDrawArcs
XSetFontPath
XAllocNamedColor
XLookupColor
XStringToKeysym
