Subject: Keep client-side decoration clicks out of nested applications
Bug: https://github.com/ValveSoftware/gamescope/issues/2299
Forwarded: https://github.com/ValveSoftware/gamescope/issues/2299
On compositors without xdg-decoration support, libdecor creates client-side
surfaces owned by the Gamescope Wayland connection. Pointer button callbacks
for those titlebar and resize surfaces consequently also reach Gamescope's
input thread. Forwarding a decoration press to the nested application can
leave its button permanently held because libdecor consumes the matching
release while performing a move, resize, or maximize operation.
Only begin nested button sequences while the pointer is over Gamescope's
actual toplevel surface. Track those presses so their releases are delivered
even if the pointer or keyboard focus changes during a game-originated drag.
