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.

    Since no one mentioned these obvious mistakes yet: is your monitor cable plugged into your 7600XT, and not into the mainboard? Did you check your discrete and integrated GPU usages to make sure the programs are using the correct one?
