I've got something using around 14hb of ram and I don't know what. I tried closing everything down and still those 15gb are in used.
In htop my biggest proces is xorg with 181mb RES.
I don't know how to troubleshoot this.
Sorry for the photos instead of the screenshot but I closed everything down.
I had apllications shutdown for lack of memory especially if I play a game that eat up alot of ram.
I'm on a linux zen 6.11.4-zen2 kernel
5700g and 5700xt
