Now that Compton has been integrated in Ubuntu Mate 16.04, I just noticed an issue.
In Mate Tweak, I’ve set Compton as the compositor but I also have my own ~/.config/compton.conf because I want to set specific options for my system.
The problem is that if I start my session, Compton seems to use different options than when I kill it and restart it from a terminal. I noticed it because of a software that sets an overlay that apparently gets a shadow from Compton and displays fine when killing/restarting Compton manually.
I assume than when launching it manually, it gets its options from my config file, so when started by Mate (I don’t know how) it uses its own options. Is that correct?
EDIT: someone pointed out to me that Mate in fact can use a file named marco-compton.conf. Shouldn’t it use the usual compton.conf instead? It’s a bit misleading to have a specific config file.
