From this answer, I managed to lower the problem concerning "Focus & Raise Behaviour" = "Very High", by using the "opacity, brightness and saturation" plugin setting "any" window to 95% opacity.
The problem is, it also matches
xscreensaver, and this wont work here:
(any) & !(class=xscreensaver-demo | class=xscreensaver | class=Xscreensaver-demo | class=Xscreensaver)
So when it activates, I can see my desktop windows thru the xscreensaver!!! what I do now?
I tried to track xscreensaver window class using
xprop but "the window" (is it a window?) cant be found by
xdotool after I get the pid of xscreensaver or its child (the actual running screensaver) and try to find its window id as that cant be found...
