Using a supported version?

  • I have searched open and closed issues for duplicates.
  • I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

I have installed signal-desktop 8.26.0 on Debian 13 and got this error:

[1] 5770 segmentation fault (core dumped) signal-desktop --enable-logging --log-level=63 -v=63 [5808:0100/000000.318758:VERBOSE1:components/viz/service/main/viz_main_impl.cc:87] VizNullHypothesis is disabled (not a warning)

Rolling back to 8.25.0, and it worked. I can provide additional information if needed :)
