I am using build 2049 of sublime merge and git for windows 2.31.0. I have gpg setup (using gpg from the git installation) and a repo with signed commits. Whenever I select a signed commit, the ‘Signature’ field displays 'Loading…" and then I am unable to do anything in sublime merge. I can click around but cannot perform any command like checkout another branch, commit something etc.
If I then try and shutdown sublime merge then the task never ends and I need to kill both the sublime merge task and the gpg task. Switching off gpg in my git config solves the problem, so it appears it is a problem with trying to verify the signature in sublime merge.
