Yeah you're full of shit, sorry but I've never heard of any of these issues happening. The only thing I can think of is you used the wrong ISO that wasn't for Nvidia or something. Also, you want HDR then use KDE, so you want something like KDE Neon or Kubuntu. As for fonts looking like shit, again, it's all down to your drivers would be my guess, meaning you're the one who downloaded the wrong ISO for pop_os. I'm running an all AMD build, maybe you should look into that I guess if you literally can't click install on the hardware drivers applet in any modern Linux distro.
