I need some help here.
Yesterday i tried to install a specific patched version of Wine1.9 that came with the Gallium drivers. After that apt-get had a small stroke because it could not remove Wine.19 anymore. But after resolving that and a restart now suddently all my system icons are all tinted red.
The Steam Logo is fine in Caja and then turns into that weird reddish one on the dock, Also note how the dock widget actually displays the icons correctly.
System: Ubuntu MATE 16.04.1 LTS, http://www.sysprofile.de/id190570
It seems that Wolfmans solution is the only working fix for right now:
Until we find out what is going wrong i strongly advise not to touch MESA or any other part of the grafics drivers.
