I have installed ST3 with Package Control on Ubuntu 20.10. Extensions: Twig, Emmet, SFT.
Then during work Sublime hangs very often. No matter if in typing, opening files or saving.
I can then only solve this by pressing Alt-TAB. Otherwise it takes up to 30 seconds until I can use Sublime again.
Under MacOS ST3 runs completely without problems with these extensions.
Is there any help for this?
