I am also getting segfaults when trying to start Nageru on my computer
(old AMD card).
Whether Nageru is ever expected to work on my or Antonios computer is
one thing.
But failing with a segfault is clearly a bug in the error handling.
It is fine to display a window "Sorry, your hardware is not supported",
segfaulting just causes user confusion. [1]

start getting many automated crash reports
