Recently bought a RX7600XT and experienced lagging in Krita and flickering in blender since. I installed the drivers from AMD’s website, and ROCm.

I am unsure and totally overwhelmed as to what could cause these issues. ChatGPT always wants me to edit /etc/default/grub, but I am not sure why and what the bootloader has got to do with it?

These are quite a lot of questions and few information. If you need anything I am more than happy to provide any information.
