Nope. Had the latest mesa drivers I could get and it still didn't work.

I ran into this exact same problem and spent a painfully long week trying to fix it. Unfortunately I couldn't... My only solution was to switch distros and the problem disappeared. I went with Fedora and now every game works like a dream. I still don't know what the issue was but it seems to be something to do with having an AMD system and using steam on Ubuntu.
Probably not the solution you're looking for, but it is a solution!
Been there!
A character suddenly gets a lot of emotional backstory indicating they are about to die.
I like how the figures look like they're desperately trying to come up with some reason why unions are bad.
I had this dread too! I thought it would be incredibly time consuming but it ended up being a 30 min job (when I'd spent at least 4 days trying to make steam work on Ubuntu). Distro hopping is definitely one of the best features of Linux.
I'm not sure if mint is completely the same, but on Ubuntu you can easily make a bootable USB of another distro using this method: https://ubuntu.com/tutorials/create-a-usb-stick-on-ubuntu#2-requirements
You'd then back up your data, and restart your computer and then, depending on the computer, it might either start the distro installation or you'll need to go into bios and configure your computer to boot from USB.
It sounds more complicated than it is, but there are lots of online tutorials to show you how to do it. Just make sure to back up your data first just in case.
I had the exact same problem with Ubuntu trying to get steam games to run. Unfortunately I could not resolve it and was advised to move to another distro. I chose Fedora and now everything works perfectly without having to make any adjustments. I know it's not the answer you're looking for, but it is a solution.
One of my favourite sci-fi books of all time. I managed to have nothing spoiled and was stunned by the direction the book went in. Loved it.
I've started to feel dirty clicking on icons like some sort of peasant.
I did, but only by installing another distro (Fedora).
He's amazing on the comedy podcast Comedy Bang Bang.
