Comment 2 for bug 1758009

FYI
Apparently more people are affected, a high amount of visitors since March 2018 on this Askubuntu page, describing the same symptoms due to a bug January 2018. #1735594

https://askubuntu.com/questions/992571/gui-unity-crashing-in-16-04-lts-after-updates-2018-01-04-compiz-segfaults

This bug has the same symptoms, but is less severe and segfaults in libcompizconfig not compiz:
 kernel: [ 554.941900] compiz-config-p[3736]: segfault at 657461746f72 ip 00007fb7a2350d6f sp 00007fffa4bef830 error 4 in libcompizconfig.so.0.0.0[7fb7a2328000+52000]

Workaround: use low graphics mode, see workaround 3 on the Askubuntu page.
