I’ve seen other comments suggest possibly trying a different distro, if that is the case I’d highly recommend Pop!_OS. They have an Nvidia specific ISO that works brilliantly, I’ve not had any issues with it.
Definitely comment more than I did on Reddit. I feel like if I comment on Reddit post that has been up for a couple hours, my comment will never get seen – haven’t seen that here
With regards to 6. I tried Xerolinux with a rice on it and yes it looked pretty but after a couple hours of real world use it was more annoying than anything else.
Just had a Quick Look on mobile and this seems to be more like a Figma alternative (still very used to know though). Canva is more like a online (and simplified) Gimp/Photoshop alternative.
