GLX backend showing blank screen on AMD GPU

I currently have an ArchLinux install with i3wm and xf86-video-amdgpu driver installed on my PC. When I run Compton with the xrender backend it works fine, however when I run it with the GLX backend I can only see my background (feh) and nothing else. Running on an AMD Radeon HD 5670. My config:

# General
daemon = true;

# Shadow
shadow = true;
clear-shadow = true;
no-dock-shadow = true;
no-dnd-shadow = true;

shadow-opacity = 0.75;
shadow-radius = 8;
shadow-offset-x = -12;
shadow-offset-y = -12;

menu-opacity = 0.85;
inactive-opacity = 0.85;
active-opacity = 1;
frame-opacity = 0.6;
sw-opti = true;

shadow-exclude = [ 
  "_NET_WM_STATE@:32a *= '_NET_WM_STATE_HIDDEN'",       # hidden
  "bounding_shaped",                                    # shadow-ignore-shaped
  "class_g *= 'Dmenu'"
];

# Fading
fading = true;
fade-in-step = 0.1;
fade-out-step = 0.04;
fade-delta = 20;

# Opacity
backend = "glx"
opacity-rule = [ 
  "90:class_i ^= 'scratchpad_' && !_NET_WM_STATE@:32a",   # scratch 90%
  "0:_NET_WM_STATE@:32a *= '_NET_WM_STATE_HIDDEN'",       # hidden 0%
  "0:class_g = 'Transparent Conky'"              # lemonbar placeholder
];

vsync = "drm"


# GLX backend
glx-no-stencil = true;
glx-copy-from-front = false;
glx-use-copysubbuffermesa = false;
glx-no-rebind-pixmap = true;
glx-swap-method = "copy";
glx-use-gpushader4 = true;
xrender-sync = true;

What could be causing the problem?

No one responded to this in the past 3 months... Wow.

Have you tried removing all .conf lines except backend = "glx";?

AMD produces atrocious Linux drivers for their graphic cards. This is especially true for their binary blob (Catalyst) driver which I heard is now discontinued (?). I don't know how good their open source driver is, but I'd suggest it is of the same garbage quality.

If you want to use Linux, do your best to stay away from AMD products.

Just ran into this. :\
