This constantly happens here, I just have to run steam with --reset on terminal so it deletes and redownloads all steam stuff from user directory (except games). It always fixed the issue.
Wow I didn't know about that option! I always removed everything (but steamapps) from ~/.steam to fix issues.
Thanks for the tip!
12 hours ago it was fine. Maybe give it some more time? It had to download some stuff
I just updated Steam on Linux MX and works fine for me.
Tho I've read they implemented hardware acceleration in this patch, maybe you can try temporarily disabling it and see if it fixes the loading?
