Hmm, I have disabling the window geometry text in Window Display settings and it seems the segfault was gone (with default theme).
I noticed some sequence that trigger the segfault (the sudden Moksha restart). Note that this happens only in Detorious theme. This sequence seems doesn't trigger the segfault in default theme.
So here's the sequence.
[The Sequence, triggered only in Detorious theme]
(Right after booting my machine)
Settings > Settings Panel > Windows > Clicking random items there > sudden Moksha restart
(sometimes I succesfully enter, lets says, Window Display and changing something there, but usually the segfault suddenly occurs just right after that. When it happen, my changes didn't saved at all)
Note that I'm using Lenovo idepad 110 with Bodhi 4.0.0 64 bit, standard edition, kernel 4.9.5-040905 generic, updated MESA to 17.1, and doing regular apt-get update.
