Welcome to Linux. I run mint and had screen tearing issues as well. Turns out mint detected my monitor correctly, but it had the wrong refresh rate. Once I set that to the correct refresh rate, my screen tearing was fixed. So I suggest checking that.
Here’s my anecdote. I have Kaiser through my employer and pay about $200 a month for the best plan offered. I pay $10 for a 30 day supply of generic medication. Video/phone visits are free. I recently had to get lab work done twice and paid $90 combined for both, but I was able to just drop by whenever was convenient for me and was in and out in 10 mins. I had a mental health crisis last year and went through weeks of intensive outpatient group therapy plus months of ACT/DBT therapy all for free. My individual therapist is covered and I pay nothing. I recently had a physical exam, it was covered. Now I do have an autoimmune disorder that I do feel a bit neglected a bit by them, but I could advocate for myself more.
So from a non major life threatening emergency perspective, I feel pretty satisfied with my insurance.
