Description kellyc 1999-11-11 19:21:21 UTC
When our application is run on 24-bit with Red Hat 6.0 and XFree86 3.3.3.0
the red and blue color planes are swapped.  So if RGB is 255,0,0 you get
blue and if RGB is 0,0,255 you get red.

We don't get this behavior on UNIX or Windows. (Yes, I know one's an OS and
the other's a windowing system.)

Is this fixed in XFree86 3.3.5.0?

If it's not an XFree86 problem do you have any clue why this would happen?

Thanks!

what video card are you using?  Chances are *very* likely this was fixed in 6.1.

another solution would be don't use 24 bit mode, use "32 bit mode".  32 bit mode
is really 24 bit color as far as X is concerned, the data is just passed to the
card differently.
