            Bug ID: 16192
           Summary: custom Application Shortcuts ignored while focus is at
                    :0.1
    Classification: Xfce Core
           Product: Xfce4-settings
           Version: 4.14.1
          Hardware: PC (x86_64)
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Medium
         Component: Xfsettingsd
          Assignee: xfce-bugs at xfce.org
          Reporter: dbtx at mail.com
  Target Milestone: Future

I use two graphics cards, two monitors, and two active X11 Screens. I set a KB
shortcut "Super+F1" to run a command, bin/subscreen.sh:

#!/bin/bash
export DISPLAY=:0.1
exec xterm 

The xterm window appears on the second monitor and is immediately given focus
(I keep the 'focus new windows' switch on). I can use it to launch more
programs whose windows naturally appear on the same monitor, and I can Alt+Tab
between them, also only on that screen & monitor. 

The symptom is that no matter how many times I press the key combination, I
only get the first xterm unless I click the mouse (still on :0.0) to return the
focus (and again each time I want a shortcut to work). I also made a one to
launch mouse-switchscreen [1] which "teleports" the mouse pointer between the 2
screens, as these are disconnected (not adjacent) in the server layout. This
shortcut only works in one direction, only while anything on :0.0 has focus.
After using it, in order to get the pointer back to :0.0, I have to run the
command manually in that xterm (or a text console on other vt, or via SSH,
using DISPLAY=:0.1 mouse-switchscreen). 

Since it uses the current value for DISPLAY to derive which screen it will
switch *to*, making that particular program work "normally" with that shortcut
would also require changing the environment handed down to each launched
application so that DISPLAY matched whichever screen had focus when the key
combination was registered. While that's admittedly a very specific corner
case, it seems appropriate to have newly launched applications be placed on the
"current" screen in the same way, or for the option to be available-- which of
course any command or launcher can still override, just as I did for xterm.

Steps to Reproduce:
- In Window Manager settings, Focus tab, enable "Click to Focus" and 
"Automatically give focus to newly created windows"
- configure 2 separate X screens and restart machine (or just display manager)
- run "DISPLAY=:0.1 <any-GUI-program>", taking the focus to 2nd screen
- attempt to use any Application Shortcut, e.g. Alt+F2 for Application Finder

Actual results:
- none

Expected results:
- window for application bound to the shortcut opens on 2nd X screen

OS: Gentoo (unstable ~amd64), kernel: gentoo-sources-5.3.11
HW: Athlon FX-8320, Nvidia GeForce GTX 780  and GeForce GTX 1050 Ti, official
binary driver version 440.31, USB mouse & keyboard
