scrolling is buggy

What happened?

Scrolling inside the notebook is acting weird from time to time. Sometimes, scrolling up freezes, sometimes scrolling down, and oftentimes, both directions. The issue goes away when you look at empty cells. Moving to another tab with a notebook or .py file, the issue doesn't persist.

Here's a video showing the behavior.

I'm not sure if it's default or at some point I changed them: the followings are set:

"workbench.list.smoothScrolling": true, "terminal.integrated.smoothScrolling": true, "editor.smoothScrolling": true,

Also, when this issue happens, I cannot select the notebook output, double clicking on the results also doesn't work.

what renderer is being used for those outputs (select "change presentation" from the output menu as in the screenshot below)? Do you have some easy to repro code that generates an output that causes this?

The first one is active. I don't know exactly when this happens. Sometimes, when multiple large figures or interactive plots, like maps, are shown and I frequently scroll up and down, it freezes. I let you know if I can find an easy repo code.
