I opened Sublime Text 3 recently on my computer that runs Arch Linux and the text on the tabs and bottom bar looks like they've been cut in half horizontally.
I tried uninstalling the sublime-text and reinstalling it. Same result. I also tried removing the package and installing the sublime-text-4 package. Same thing.


Playing with your font settings in your preferences should fix the issue. Edit Sublime font preferences
I would also check through your installed linter(s) and see if they may be causing the issue.
Lastly check your computer's display settings and make sure your scaling is at 100% (probably not the issue at hand but worth a check).
