What are you running Zwift on? Those graphics look like something from the Sega Genesis/Mega Drive console to me 
It’s a photo of my TV screen, not a Zwift image. 4K TV.
Tried windowed mode and dropping the resolution to 1440, no change. Still getting black foggy patches (only) when using Zwift.
Getting black squares with Yumi coming into the desert, night, wet road spray but not actively raining.
Still get the black square still, temp with coco…

I had black squares on Hilly KOM Reverse race yesterday morning.

Logic says if it is not visible in a screenshot and only on your screen, then there is a problem with your hardware setup.
Nothing to do with colour settings on the TV? How about other applications?
Hi Chris, as long as I shut the PC down after using Zwift (I only use/used it for Zwift) eg Restart> Shutdown, I’m not getting the issue. Thanks anyway.
Already tried changing the video cable and different ports on the GPU? Do you have another display in the house that you can test with? The fact that the screenshot is correct makes me think it’s something between the GPU and the display. Have you already gone through the recommended settings in the ZPCMR guides? I have your same video card, as do many others, and I’ve never seen anything like that nor heard it reported by anyone else.
Thanks Paul. I’ve got everything as recommended, don’t have another card to try, but am ok with work around.
Yeah, still got some squares on the flat section near the Hilly KOM banner, no other riders nearby.
Much less black/red/yellow squares of late. But have also noticed that the rear lights on bikes are turned off except for your own bike in recent weeks.
Seems logical, given most squares appear in the position of the rear light and that the issue seemed to start when the autobraking feature rolled in one of the many pack dynamics updates and then got worse the longer the play controllers were out. (More people with ability to brake to stay in pace partner groups, accidently braking when trying to steer etc…)
Just turn off the rear light completely ZHQ, we don’t need it. 
Black and colored squares are back in a big way with the release of 1.69, in more conditions than ever

I have observed the same.
Yeah, I’ve seen them in the desert as well. Plus there has been this one occurrence in France (between the spawn point and the first intersection) that has never gone away after the first time the squares were everywhere.
I see them here often also. I notice the square stays fixed as you turn, which makes it seem like a rendering issue with one of the bushes.
