regolith-desktop Screen tearing due to no Picom config being loaded on boot

Screen tearing due to no Picom config being loaded on boot

[X] I've run a search on the existing bug reports to make sure I'm not filing a duplicate (you can use the search box at the top left corner)
[X] I've read the Regolith documentation and didn't find any relevant topic
[x] I tried asking on Slack (especially for configuration related issues) (This slack link isn't working I don't think? I clicked it and didn't get to the right place)

Describe the bug Screen tearing despite updating the picom config to enable V sync (this fixes it see below)

These config changes only actually load after running

pkill picom
picom --config .config/regolith3/picom/config

I tried updating /etc/regolith/picom/config and also ~/.config/regolith3/picom/config

running picom manually after boot and pointing to my config file is fixing my issue and is my workaround for now.

To Reproduce use the default picom settings, and try to override them according to the docs here: https://regolith-desktop.com/docs/howtos/customize-compositor/

I test screen tearing with this video. It's immediately apparent if it's broken or fixed while viewing it: https://www.youtube.com/watch?v=MfL_JkcEFbE

Expected behavior regolith loads my custom config (updating the default path /etc/regolith/picom/config doesn't work either as mentioned)

Configuration file(s) Please attach or mention any customization you've done to configuration files which might have an impact on the bug you are describing. It'll help us determine the root cause of your issue.

I don't think it makes a difference but here's my config that fixes the screen tearing:
