Steps to reproduce

Expected behavior

Text appears right away, filter is updated shortly

Actual behavior

Significant lag (the whole text was typed in ~sec)

Maybe add an option not to update on every keystroke, but after some delay?

Logs

do you can record video how it happen (your video attached did not display anything)? i've never seen anything like it.

The attached video does show how it happened: the input text that is typed in ~1 second is taking ~10 seconds to appear because there is a delay after every single keystroke

And if the list is big like in the Blocklist tab, the repeat is even slower (I'm just holding the Z button, so repeat should be instant), and eventually the app just freezes - that's when the mouse reappears as otherwise it's suppressed during hanged typing (in this case it unfroze later with zzzzzzzzzzzzzzzzzzzzzzzzzzz in the input field).

So clearly the app is doing something very expensive incorrectly on every single keystroke instead of waiting until the user input is complete

This is related to slowdowns in packet logging too
