Thanks for the detailed bug report.

It looks like we were never doing quite the right thing to remove the X 
input focus when losing Windows focus.

I've uploaded xorg-server-1.19.3-1 with a fix for this.

Perhaps you could try that and see if it improves things for you?

This is also a long standing bug, but is more complex to fix.

At the moment, clicks outside X windows aren't seen by the server at 
all, hence this behaviour.
