<pre>With recent KSP 1.2 pre-releases freeze randomly unless LIBGL_DRI3_DISABLE=1 is
used. (KSP 1.1 was hardly usable on Linux due to many bugs in the Unity 3D
version used then)
I got best results (no freezes) on my Haswell laptop using the following steam
launch options: 'LIBGL_DRI3_DISABLE=1 %command%_64 -force-glcore'
As soon I drop the 'LIBGL_DRI3_DISABLE=1', the game would freeze – it could
happen as early as on the loading screen, or several minutes into the game
play.
Mesa 12.0.2, 12.0.3
Linux kernel 4.7.1
libdrm 2.4.70
KSP builds 1.2.0.1473 – 1.2.0.1517
The same freezes happened on my work PC – Skylake-based.
KSP bug report: <a href="http://bugs.kerbalspaceprogram.com/issues/11420">http://bugs.kerbalspaceprogram.com/issues/11420</a>
It might be another Unity 3D bug, but it might be a driver problem.</pre>
