Description manuelchaves 2019-06-04 00:01:45 UTC

(I'm not sure if this is the right component, I had no idea where to put this)

STEPS TO REPRODUCE
1. Have 2 monitors
2. Click on a icon only task in the taskbar of the first monitor to launch an application

OBSERVED RESULT
Sometimes it starts the applications in the second monitor.

EXPECTED RESULT
It should always start in the monitor where it was launched.

Comment 3 Vlad Zahorodnii 2019-06-04 20:54:49 UTC

Okay, it seems like mouse focus is moved to a client on the other screen for a brief moment.

You could either:
(a) Use a window rule to position the desired client;
(b) Enable "Active screen follows mouse", it's under Window Management, Window Behavior.

Though if the client specifically sets its position, I don't know how to deal with that case (perhaps create a window rule to disobey geometry requests?).

Windows Follow Mouse works, as long as I don't move the mouse elsewhere. But it's an improvement.
