This script makes opaque all windows that are currently completely transparent. Compton sometimes sets the transparency of windows to zero, so this helps get out of when this happens.

Upon further testing, the following addition to compton.conf seems to fix the issue:

opacity-rule = [ 
    # If not hidden and active (active-opacity)
    "100:!_NET_WM_STATE@:32a *= '_NET_WM_STATE_HIDDEN' && _NET_WM_STATE@:32a *= '_NET_WM_STATE_FOCUSED'",
    # If not hidden and not active (inactive-opacity)
    "80:!_NET_WM_STATE@:32a *= '_NET_WM_STATE_HIDDEN' && !_NET_WM_STATE@:32a *= '_NET_WM_STATE_FOCUSED'",
    # Hidden
    "0:_NET_WM_STATE@:32a *= '_NET_WM_STATE_HIDDEN'"
];

Using active-opacity or inactive-opacity on their own doesn't make a difference and using the latest i3-gaps doesn't fix it either but the above works for me.
