--- Comment #5 from Mario Kleiner mario.kleiner@tuebingen.mpg.de --- Can you try what happens if you add the following snippet inside the <device> section of your /etc/drirc and restart compton?
<application name="compton" executable="compton"> <option name="allow_rgb10_configs" value="false"/> </application>
The output of xdpyinfo and glxinfo could also be useful.
To disable the new rgb10 support globally, one can add this snippet instead:
<option name="allow_rgb10_configs" value="false"/>
