Running steam in Xwayland rootful makes Xwayland window partially clickthrough
I've reproduced this in multiple compositors:
- Xwayland :99
- DISPLAY=:99 i3
- Ensure that the Xwayland window is floating above some other window that accepts input
- DISPLAY=:99 steam
Input to the Xwayland window outside of a small rectangle (maybe 200px) in the top left instead goes to the window below the Xwayland window. (Sway does not seem to implement clickthrough. There, it causes sway to instead move the window.)
The affected area changes when the window is resized.
