vscode: Duplicate app icons in app switcher on mac

Issue Type: Bug

Mac OSX 10.15.3

Since the last update, when I use “command + tab” to switch applications, VS Code shows up twice in the list. Quitting one of them quits both. One of the icons can be clicked, but it does not open the application. So it’s as though there’s one correct icon and one decoy.

VS Code version: Code 1.63.2 (899d46d82c4c95423fb7e10e68eba52050e30ba3, 2021-12-15T09:37:28.172Z) OS version: Darwin x64 19.3.0 Restricted Mode: No

This has been happening to me for the last few versions as well! When I force-quit the extra icon a message says “Extension host terminated unexpectedly”.

Used extension bisect to track the issue down to ban.spellright:

Extension Bisect is done and has identified ban.spellright as the extension causing the problem.

Root cause seems to be https://github.com/microsoft/vscode/issues/138712#issuecomment-1002267673

I’m having the same issue VS Code showed thrice in the app switcher

Bisect removed one of them but VS Code still shows twice there and twice in the applications dock https://streamable.com/9bmcae

OK OK. I know you have 128GB RAM. Don’t upload this image next time. 🙄😂🥺🤣 BTW, OMG 3 in the app switcher. That’s …eh, interesting.

Disabling this spell checker plugin finally fixed it for me ☹️ https://marketplace.visualstudio.com/items?itemName=ban.spellright
