DESCRIPTION
I have a 2 monitor setup, the primary one is horizontal 1440p@125% on the left
and second is a vertical 1080p@100% on the right.
Whenever I have a maximized XWayland window on the primary display, when I move
my cursor against the top edge of the screen, I can click through to the window
behind the maximized one.
This is an obvious flaw that causes a terrible UX inconvenience.
This issue is only present when the maximized window is XWayland one and
doesn't occur with Wayland native windows. It also doesn't happen when
fractional scaling is disabled on the primary monitor.
STEPS TO REPRODUCE
1. Make sure your setup is similar to the one described above.
2. Maximize a native Wayland application.
3. Maximize an application that uses XWayland and make sure it is in the front.
4. Move the mouse cursor against the top edge of the horizontal display on the
left.
5. Left click with the mouse.
OBSERVED RESULT
It clicks on the native Wayland window behind it.
EXPECTED RESULT
It should click on the maximized XWayland window in the front.
