Those tests are for CI only. We cannot guarantee reproducible results on all OS'es.

[Songtronix]

Oh. Sorry for that, didn't know that. However I hit a PlatformError when using https://github.com/Aloxaf/silicon that's why I ran the tests.
Do you know how to debug a PlatformError? See Aloxaf/silicon#5 for more information. Could it be a missing font or such?

[RazrFalcon]

This is a separate issue. Could you duplicate a one from silicon?

[Songtronix]

@RazrFalcon you mean copying the issue over here?

[RazrFalcon]

Yes. Create a new issue with the same backtrace. I've already reproduced it on my machine.
