Details:
When running GNUstep applications on a x86 machine and displaying them on an
X-server running on a PowerPC machine or vice versa, all pixels either lack a
byte swap or or are swapped once too often. See the attached screen shots of
Ink's color panel. Apparently ARGB get displayed as BRGA pixels. Neither the
art nor the xlib backend suffer this problem. The X-server has depth 24.
Out of curiosity I also tried to run the server in 16 bit mode, but the cairo
backend does not work in this configuration (neither locally nor remote),
reporting the error:
Cairo status 'invalid value for stride' in DPSinitgraphics
