I’ve been seeing screwy graphics like this pretty consistently, probably since the last update. Is there a way to fix this without reinstalling Zwift?
Can you provide a complete rundown of your setup?
Windows 10
Intel(R) Core™ i7-8700 CPU @ 3.20GHz
16 GB RAM
AMD Radeon RX 550
1920x1080
Zwift version 1.23.3 (100641)
Usually points to corrupt assets or cache. Fully reinstall the game.
I finally got around to reinstalling Zwift yesterday and… it didn’t help. Followed all steps and deleted folders as outlined here: Re-Installing Zwift.
Use DDU to fully uninstall the Radeon driver and use one of the older ones verified as fine by @Alex_Beebe. If it’s still the same after that then I’d suggest a hardware problem, probably with the VRAM on the graphics card.

Before doing all that it’s worth trying to delete your shader cache in the Radeon driver: Global Settings > Reset > Shader Cache > Yes
See if that helps.
Good tips, thanks. I’ll try that later. If those don’t work I’m buying a new gaming PC 
. Been trying to justify that purchase for years lol.
Heh, just buy a GTX 1050 Ti if so. Straight swap, Ultra profile and good for 60fps at 1440p. Rest of your setup is fine.
I cleared the shader cache and updated the Radeon driver. Not sure which one did it, but it’s fixed now.
