Extreme cursor jitter in build 4213

[jhaungs]

This latest build, and the one before, have an alarming cursor jitter simply moving the cursor around on the screen. The cursor rapidly switches between the system pointer and the I-Beam text cursor.

I’m on macOS 27.0, but this happened on 26.x as well.

I’ve tested it with multiple file types, and it does not seem to be dependent on the file type/extension, LSP, etc. As of 4213, it happens constantly.

Here is a link to a small video of the problem:

If this is a known problem that is due to some package, I’m happy to remove or upgrade it.

We’ve had reports of this in the past, but since it survives Sublime Text restarts this is most likely a longstanding macOS bug. I suggest restarting your computer and seeing if it still happens afterwards.
