Bug 372202

Created attachment 102114 [details]
Glitched out color, while systemsettings is fine

When running Plasma Shell on my PowerMac G5 Quad with GeForce 6600LE (possibly not relevant, will explain in a bit), the Plasma Shell is displayed with a strong blue and violet hue (possibly due to wrong RGBA mapping).

(More to be seen in the screenshot)

Note, in the screenshot attached below, the color for systemsettings is normal, but everything else is quite messed up. This also applies to QML-based KDE applications like Plasma Discover.

So at first I thought that this was a nouveau issue on big endian machines, therefore I have opened a bug report here: https://bugs.freedesktop.org/show_bug.cgi?id=98630. However, after trying on the "fbdev" driver - which gives the same coloring issue - I thought I should let you guys know about this issue.

This issue also applies when running Plasma Discover on another desktop environment like XFCE - which has all the right color displayed - but it would be really nice to have KDE working on my G5 anyways, as it does appear to run quite quickly.

-----------------------

A quick lspci (probably trivial, but I don't have another big endian machine to test this on, so here you go):
