MC 1.19.2
It seems to be focused on the Environmental Controller block and disappears/reappears depending on whether it has modules installed or is powered. I figured it's probably RFToolsUtility related, but I'm not sure. This is on ATM8 which I slightly modified, this is the modlist.
If it is from RFToolsUtility, there any way to toggle/disable this effect?
