Wrong Input Window For Mouse
When switching between windows (e.g. PyCharm to Chromium or gnome-terminal) the input focus for the mouse (not the keyboard) is still stuck on the previous app. I can force a switch by activating the context menu (right click) and closing it again without any action. This happens on both Wayland and on Xorg, interestingly Xorg seems worse from a usage perspective.
Sometimes (rather rarely) the mouse cursor is also not visible until the foreground app is reactivated.
It seems that I'm mostly experiencing this when multiple monitors are connected and one monitor is in portrait mode. Sloppy focus is in use so it may also be related to #318 (closed)
Ubuntu 18.04.1, mutter 3.28.3
