@amanzer @sszuecs oh. i didn't grok @sszuecs's comment, I was sure there was some misunderstanding but I couldn't figure out how! But your explanation explains the misunderstanding perfectly! So yes, the switch is called "--background=" and you can override the background color with that, or you can assign an empty string to disable the tinting altogether.
@pid_eins @sszuecs Next up, adding "--background=magenta" to my run0.rc. 😂
