Any confirmation boxes in the app (i.e. the confirmation box to force push to sync service or to delete a project) shows empty boxes instead of actual text, as if the font is missing.
I’m running everdo 1.5.3 using the snap package on fedora 33, though this issue has been around since before i upgraded to fedora 33 from fedora 32 as well.
Looks related to this issue Snaps show squares instead of fonts - snapcraft.io
Need to look into it, but there’s a potential workaround mentioned.
That definitely seems like the same problem to me. unfortunately, after following the instructions found at that link it still doesn’t work properly 
It seems to be a widespread problem with snaps.
