keybindings.json causes UI to freeze for several seconds #77882
Description
- VSCode Version: 1.36.1 (also repros on insiders build)
- OS Version: macOS Mojave 10.14.6
Steps to Reproduce:
- From the command pallete, choose "Preferences: Open Default Keyboard Shortcuts (JSON)
- The UI freezes for several seconds.
- Switch to any other tab.
- The UI freezes for several seconds again.
While the keybindings.json file is open, it will continue to freeze when switching between any two tabs.
This seems to be caused by the code that's populating errors in the Problems panel for the keybindings. It seems like a separate bug that VSCode ships with problems in the default keybindings, but regardless, any problems there shouldn't cause the UI to freeze like this.
It also happens if you have errors in the user-generated keybindings file. The more errors, the longer the UI freezes.
Does this issue occur when all extensions are disabled?: Yes
