Usage

A note for the -b flag. It can cause display to freeze at least with xf86-video-ati and /etc/xdg/compton.conf

Autostarting section needs simplification or to be removed altogether. Ubone (talk) 17:58, 28 December 2017 (UTC)

Out dated

Is Compton#Firefox working for you? "class_g = 'Firefox' && argb", is not working for this, compton --version v0.1_beta2.5 ― Ubone (talk) 14:45, 2 August 2018 (UTC)

I also couldn't get Picom#Firefox to remove shadows from Firefox recently (by adding "class_g = 'Firefox' && argb", to the shadow-exclude array), which used to work earlier, so I looked into it. Turns out, the WM_CLASS variable for Firefox had changed from 'Firefox' to 'firefox' sometime in between. Then, when I used "class_g = 'firefox' && argb",, presto, it worked. The shadows were gone. It seems the problem was that the class_g variable for the Firefox window changed from 'Firefox' -> 'firefox'. Also, I think the WM_CLASS for Firefox ESR is different, but that's just my speculation.
Bonus tip, to find out the WM_CLASS for Firefox (aka class_g as specified by Picom), I used the command
$ xprop | grep "^WM_CLASS"
and then clicked on the Firefox window. -- CodingPotato (talk) 09:50, 12 April 2020 (UTC)

move

Revert the move back to Compton. This is a fork of the now inactively developed Compton. The Compton page can have a note that it's been succeeded by Picom --Ubone (talk) 07:21, 18 November 2019 (UTC)

Arch does not package compton any more, so it does not make sense to keep the old name of the wiki page. -- Lahwaacz (talk) 09:22, 18 November 2019 (UTC)

Deprecated options

With the new release of picom, some deprecated options we're removed and, if used, will prevent picom from launching. This is the case when using the suggested compton-conf tool to create these files. And, as noted here (https://github.com/lxqt/compton-conf/issues/150), the developers don't intend to adapt the tool to make picom-compatible files. Thus, the recommendation to use of this tool should be removed and, if possible, recommend other available tool.
