Hmm, interesting. I've rolled back the release for now, or you can try snap revert alacritty while we investigate a bit more.

[DanielArndt]

Similar issues for me with the candidate release (115), but the latest stable does work now that it is rolled back (I have to unset LD_LIBRARY_PATH to get some things working, though).

[jnsgruk]

@samuelabreu @DanielArndt see #18 - can you give the latest version in latest/candidate a try and see if it solves your issue?

[samuelabreu]

After snap refresh alacritty --candidate i could launch alacritty successfully.

alacritty --version
alacritty 0.13.1 (fe2a3c56)

Thank you

[jnsgruk]

Excellent! Thanks!
