Hi guys. So, I installed compton on my 13.2 Xfce install, because, well, it works better than the default compositing in Xfce. But i have an issue with compton (presumably) drawing out double shadows on some windows/menus. Now, i pretty much located what the problem is, but it's beyond my level of understanding, so i need some copy/paste advice. The problem is exactly the same as described here:

https://github.com/chjj/compton/issues/189 - and it seems there's a workaround there to put into the compton config to make it work.

And my compton config is the following:

backend = "glx";
paint-on-overlay = true;
glx-no-stencil = true;
glx-no-rebind-pixmap = true;
vsync = "opengl-swc"; 

# These are important. The first one enables the opengl backend. The last one is the vsync method. Depending on the driver you might need to use a different method.
# The other options are smaller performance tweaks that work well in most cases. 
# You can find the rest of the options here: https://github.com/chjj/compton/wiki/perf-guide, and here: https://github.com/chjj/compton/wiki/vsync-guide

# Shadow
shadow = true;			# Enabled client-side shadows on windows.
no-dock-shadow = true;		# Avoid drawing shadows on dock/panel windows.
no-dnd-shadow = true;		# Don't draw shadows on DND windows.
clear-shadow = true;		# Zero the part of the shadow's mask behind the window (experimental).
shadow-radius = 7;		# The blur radius for shadows. (default 12)
shadow-offset-x = -7;		# The left offset for shadows. (default -15)
shadow-offset-y = -7;		# The top offset for shadows. (default -15)
shadow-exclude = [
 "! name~=''",
 "class_g ?= 'Notify-osd'",
 "class_g ?= 'Cairo-dock'",
 "class_g ?= 'Xfce4-notifyd'",
 "class_g ?= 'Xfce4-power-manager'"

# The shadow exclude options are helpful if you have shadows enabled. Due to the way compton draws its shadows, certain applications will have visual glitches 
# (most applications are fine, only apps that do weird things with xshapes or argb are affected). 
# This list includes all the affected apps I found in my testing. The "! name~=''" part excludes shadows on any "Unknown" windows, this prevents a visual glitch with the XFWM alt tab switcher.

# Fading
fading = true; # Fade windows during opacity changes.
fade-delta = 4; # The time between steps in a fade in milliseconds. (default 10).
fade-in-step = 0.03; # Opacity change between steps while fading in. (default 0.028).
fade-out-step = 0.03; # Opacity change between steps while fading out. (default 0.03).
#no-fading-openclose = true; # Fade windows in/out when opening/closing

detect-client-opacity = true; # This prevents opacity being ignored for some apps. For example without this enabled my xfce4-notifyd is 100% opacity no matter what.

# Window type settings
  tooltip = { fade = true; shadow = false; };
Now my question is: where can i insert the workaround in mentioned in the github, so it doesn't conflict with everything else in my config, and where would it be best to put it?

Kind regards, and many thanks.
