Title:
Wrong colors with Mesa 9.2 and Mesa 10.0 on Lubuntu 14.04 PowerPC
Status in Mesa:
Confirmed
Status in mesa package in Ubuntu:
Confirmed
Bug description:
Hi all,
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.
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.
We had a problem with wrong colors in SuperTuxKart 0.8 last year. The
Irrlicht guys have released a little hack for Irrlicht on Linux PPC
(http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=48577).
They told me that is a driver bug, and that workaround costs
performance and RAM. Unfortunately this workaround isn't suitable for
Mesa 9.2 and higher. At this time we have to install Mesa 9.1.X and
lower on new Linux distributions like Lubuntu 13.10, Lubuntu 14.04,
Debian Sid etc. It would be nice to solve this issue because we don't
need the workaround in the future.
