I noticed that my CPU spikes at 100% on all cores when I scroll through a list (or click items rapidly) within a popup window.

I can understand resource usage while actively writing code but I don't think this should be enabled when scrolling suggestions since it does not alter the code until confirmation.

You can easily reproduce the issue by opening Intellij on a fresh project with a single file. I used main.rs (rust project) and whenever I scroll or click on suggestions, all CPUs spike.

I held the down arrow for 30 seconds:

IntelliJ IDEA 2022.3.1 (Ultimate Edition)
Build #IU-223.8214.52, built on December 20, 2022
Tabnine plugin version 0.8.10

if I disable the plugin and restart Intellij, the problem goes away and if I re-enable and restart, the problem comes back.
