popup crosses screen boundary
$ pacman --query | grep wayland lib32-wayland 1.18.0-2 qt5-wayland 5.14.2-1 wayland 1.18.0-2 wayland-protocols 1.20-1 xorg-server-xwayland 1.20.8-1 $ uname -r 5.4.34-1-MANJARO
This popup issue only occurs on wayland session. NOTICE how the application (JetBrains PyCharm Pro) believes there is space on the current monitor to show the popup to the left.
NOTE: The current selection "Python Package" / "Python File" half hilite didn't seem to be an issue when I was using it but showed up in the PrintScreen capture for some reason.
