Thanks for the help, all. I'm sure this has been answered before, but it's difficult to search for a solution because of the many variations on similar symptoms.
I recently installed Jupyter Lab on my work laptop, and while I have no issues with the functionality itself, the ui regularly hangs while I'm trying to work/type. I'd say every fifteen seconds or so, the interface just stops responding for about 2-3 seconds. Anything I type in that period doesn't show up on screen, but then suddenly appears once the program is responding again. I'm getting no other signs of freezing, nonresponse, etc. besides a lack of onscreen response.
If this sounds familiar, thank you for any insight you can share on a fix.
