- Hi all,
+ Upstream report:
+ https://gitlab.freedesktop.org/mesa/mesa/issues/477
I've tried Mesa 9.2.2-1 and 10.0.1 on Debian Sid, Lubuntu 13.10, and on
Lubuntu 14.04. Unfortunately all have issued false colors in games. They
appear to be ABGR instead of RGBA, thus blue becomes green, red becomes
alpha etc.
This issue affects sdl2 applications either.
The Mesa version 11.1.2-1 doesn't work either on ubuntu MATE 16.04
PowerPC.
Mesa 8.0.5-4 and Mesa 9.1.6 have no color problem.
The transitional solution is to install the old Mesa 8.0.X with "Force
Version" with the Synaptic package manager on new distributions.
In my point of view, the problem is in the source file p_format.h in the
directory src/gallium/include/pipe/. There is some code for translating
colors for big-endian machines. The problem is, this code is only for
the CPU. I mean for LLVMpipe for the CPU. The Radeon graphics cards
don't need this translating code but IBM pSeries machines without
graphics cards need this code. This code translates the colors in a
wrong way for Radeon graphics cards. I removed this code and after
compiling Mesa again, the colors are displayed correctly. I released
some unofficial Mesa versions with this patch.
