Hi,

Just want to let you know, I did not ignore your message.
Fvwm deals with the event queue in fvwm/events.c.
Fvwm checks for matching bindings in libs/Bindings.c and
processes binding commands in fvwm/bindings.c.

So far I see nothing that accounts for bad coordinates in a button
press event or for additional mouse leave events.

I've given some thought to additional tracing in Fvwm, but so far
I haven't found anything I think would be helpful.

I'm guessing darktable could work around the issue by ignoring
button presses with negative values?

There are 2 sets of x/y positions in button press events, one
relative to the window, one relative to the screen.  Are they
both -1?
