           Summary: Text colors messed up when running with 16 bit color
                    depth and XXA
           Product: cairo
           Version: 1.4.9
          Platform: PowerPC
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: high
         Component: general
        AssignedTo: cworth at cworth.org
        ReportedBy: cnspeckn at physik.uni-wuerzburg.de
         QAContact: cairo-bugs at cairographics.org

I'm running Gentoo stable on a G4 powermac with an ATI Radeon 8500. When I run
X in 16 bit color depth, the colors of text rendered by cairo get all messed up
(looks a bit like a rainbow). Changing the depth to 24 bit or setting the
acceleration architecture to EXA cures the problem. The problem occured after
upgrading from cairo 1.2.something to 1.4.6 and is still present in 1.4.10. I
strongly suspect this to be a endianess issue...

The bug also occurred on other ppc systems, see
