Picom using high CPU

[czrpb]

Hi!

picom is using a lot of CPU and starts right up/away when logging in; it doesnt seem to wait for terminals or browsers etc.

Ive poke around the net and tried to turn off transparency/opacity in a couple of configs such as alacritty and picom, but still no go.

I do apologize for not being able to help myself and would be happy to have pointed out where I can improve!

but lts kernel

[czrpb]

Hi!

You are suggesting to try the LTS kernel yes?

Ill give it a whirl!

<< q

[SGS]

Some kernel have version 6.1 bore,amd?

LTS 5.15.82-1-lts
It's worth a try, at least to rule out the kernel as a problem.

Linux kernel 6.1 is here
