The feature "Capturing specific windows and only drawing to them" doesn't work on Ubuntu 24.04

[luxkatana]

When focusing to capture one application/window, it captures however if I want to draw on that captured application, then main screen of my laptop goes to that screen/application that is focused on.

For example I have spotify and firefox on and I have my iPad connected via weylus.

When I am working on my maind display/laptop in firefox, and I choose to capture only my spotify and I try to click on something on the screen that is focused on spotify. My main scree will go to spotify too. It'll switch from applications.
