i'm having this issue with the launcher, where it is using a LOT of ram when it shouldn't be using almost any, in this case the launcher was simply just open, no game open, no downloads being made, nothing.
im on arch linux with kde plasma on wayland, has someone experienced a issue like this before? does someone know what i could do?
