[Bug 57603] Interacting with yabridge plugins after moving the window broken

[WineHQ Bugzilla]

--- Comment #8 from PennRobotics  ---
X11DRV_MotionNotify (uses A coords), map_event_coords (A to B),
NtUserTrackMouseEvent (uses B coords), and then window_from_point (uses A
coords)

The B coord numbers are always higher than the A coord's.

X11DRV_MotionNotify refers to 0x10072/2000003
NtUserTrackMouseEvent uses 0x10076

They both seem to be the plugin window (rect 0,0 to 805,460), so I'd expect
them to use the same coords or same handle, but I guess that's the purpose of
the comparison near line 500 in dlls/winex11.drv/mouse.c

That's about the extent of my mental energy today.

There should be enough there to figure out if yabridge needs to give Wine more
information or if the mapping is happening improperly in this case.
