This problem concerns the oibaf ppa. Note that this doesn't happen with the
padoka ppa. The problem occurs once I update the

libgbm1 

package from 

Installiert (16.04): 11.2.0-1ubuntu2.2

Installiert (16.10): 12.0.3-1ubuntu2

to the respective (current) version of the oibaf ppa (I figured this out by
installing/reinstalling etc.)

My hypothesis is that this is related to llvm 3.9 <-> llvm 4.0, but I'm not
sure.
