Description David Holm 2004-12-28 06:37:01 UTC 
I have a Pegasos II PowerPC (MPC7447) with a Radeon 9100 (AGP, running in
PCI-mode since there is no agpgart module for this hardware). When DRI is
enabled I experience color corruption, for instance, the black borders around
the fonts in the GNOME menu are yellow. With DRI disabled everything is working
ok. I have also tried it with a Radeon 9200 with the same problem. The
Xorg.0.log is filled with:
(EE) RADEON(0): R200SetupTextureCP: RADEONSetupRenderByteswap() failed!

Right now I'm running Xorg 6.8.1.901 on Gentoo/PPC.

(BTW, you really should change 'Macintosh' in the platform list to 'PowerPC',
not all PowerPCs are macs you know)

I have an ATI radeon 9200 and I have the same problem:

(EE) RADEON(0): R200SetupTextureCP: RADEONSetupRenderByteswap() failed!

With color corruption.

Example of what the color corruption can look like.
Comment 4 David Holm 2005-02-08 03:27:30 UTC 
I've had a report from a guy with a Radeon 9000 that he gets the same corruption
when he enables the COMPOSITE extension, but DRI works. I have tried messing
around with both COMPOSITE and RENDER here but I still get corruption when DRI
is enabled, and no corruption when it is disabled.
