A couple of weeks ago, after an update, strange black marks appeared on the road in front of me which kept ahead throughout. Sometimes they are white but mostly black. Sometime straight across and other times V-shaped. They fade out and come back. They look a bit like tyre tracks. Is this a new feat…

What platform are you running Zwift on, and are you up to date? Is this on all maps/courses?

If you are on Apple TV there was a patch released to fix the black boxes that were appearing, make sure you check to see if you are fully updated, don’t rely on auto-update. Also, force close the Zwift app after each use.

@Yoav_Tzabar Does is look like the black squares discussed in this this thread ? If so, please update your game app. This bug was fixed.

No, it looks nothing like it. I’ll post a screenshot later today. And on my iMac, Zwift updates automatically on startup and had updated yesterday and the marks were still there.

I have a couple of screenshots and a video but this forum doesn’t seem to be able to accept upload of pictures or videos but it appears that it is possible so how is it done?

Flick em to me and I’ll post them up later today … zwiftposts at gmail dot com You probably need minimum number of posts before you can add external url’s and pics.
