Typing this on 12th gen running Fedora, and I have none of the issues you describe. I've been daily driving this laptop for 2 years, and my only complaint is the mediocre battery life (I get 5-6 hours with mixed use and around 50% display brightness).
I did switch from the glossy to matte display, which was a massive improvement for use on the go.
