GTK-3 (in xfce4) need to have there X and Y coordinates adjusted for restoring.

[PhenixDragyn]

BUG: When restoring in XFCE4 (Not sure about other DE) any app that is GTK-3 will adjust oddly on the x/y axis. When doing some debugging I noticed that GTK-3 apps will restore further down on the y access till I found if I subtract the titlebar size then it's fine. Below is a script I used to detect whether an app is GTK or not, if GTK then subtract the titlebar and border appropriately. Then restoring with these coordinates work.

Not sure if this is an option you can add to the config to detect and turn on or off for different DE's.

#!/bin/bash

entire=true

aw=$(xdotool getactivewindow)
pid=$(xdotool getactivewindow getwindowpid)

eval $(xwininfo -id "$aw" |
      sed -n -e "s/^ \+Absolute upper-left X: \+\([0-9]\+\).*/x=\1/p" \
             -e "s/^ \+Absolute upper-left Y: \+\([0-9]\+\).*/y=\1/p" \
             -e "s/^ \+Width: \+\([0-9]\+\).*/w=\1/p" \
             -e "s/^ \+Height: \+\([0-9]\+\).*/h=\1/p" )
if [ "$entire" = true ]
then
    extents=$(xprop _NET_FRAME_EXTENTS -id "$aw" | grep "NET_FRAME_EXTENTS" | cut -d '=' -f 2 | tr -d ' ')
    bl=$(echo $extents | cut -d ',' -f 1) # width of left border
    br=$(echo $extents | cut -d ',' -f 2) # width of right border
    t=$(echo $extents | cut -d ',' -f 3)  # height of title bar
    bb=$(echo $extents | cut -d ',' -f 4) # height of bottom border
    gtk=$(grep -Poi '\b(lib)?\K(gtk|qt|tk)([^a-z/]*\d)*(?=[^/]*\.so\b)' /proc/$pid/maps | sort -u)
