Bug Description

When I click in any xwayland window beyond the top-left 1024x768 rectangle, the window below is clicked.

Expected result: The xwayland window registers the click
Actual result: The xwayland window registers the click correctly only in the top left 1024x768 pixels rectangle.

Additional information:

This bug only manifests when using Ubuntu in Virtualbox.

This bug manifests when Virtualbox Virtual screen is set to scale mode

Workaround: When I set Virtualbox Virtual screen to fixed resolution the problem goes away in some apps.

In other apps the workaround doesn't help and the bug still manifests.
