Don’t know if it’s related but was going up the Alpe the other day and saw a ‘rotating tree’ and while in a workout, a workout banner would momentarily flicker onto the screen well before the interval was up.
I checked some previous versions (one from June) and it also happened, the bug isn’t new. But after the 1.30.0 update it started to happen a lot more often (enough to become annoying). Titans Grove is the easiest place to see it.
It’s definitely new IMO, it didn’t happen prior to version 1.30.0 to the best of my knowledge. I tend to notice this stuff, unfortunately for me.
Before version 1.29.1 I was using OBS in the background to prevent a similar issue (avatar flickering at high frame rates), so perhaps it’s an older issue that was resolved by OBS in the past. It doesn’t work now though.
Yes, maybe it was the OBS or maybe you didn’t notice because it happened very rarely. There’s one place in the route Sand and Sequoias, right in the beginning of Titans Grove when you can see some leaves flying in the wind, it always happens in this place using version 1.26.1, just checked.

At least five shadows there that are missing in the second frame. Good work finding a repeatable spot. 
I bet OBS fixed it before, and whatever change they’ve made (so that OBS isn’t required) doesn’t go quite far enough to address the issues it resolved.
What do I need to do with OBS? Just using it to record doesn’t seem to make difference (1.26.1)
OBS doesn’t work to resolve this issue.
You just said it did. I’m using previous version of Zwift, not current. So I guess this issue is unrelated to the avatar flickering which was fixed by OBS (I never had it).
Another spot using 1.26.1
Huh, what I said is I never experienced this particular shadow issue before the most recent update. But I was always running OBS before, for other reasons. OBS clearly doesn’t resolve this issue, so whether it’s old or new, the fact is its present now and requires a fix. There are often server end changes that affect the game btw, so it might be unrelated to the update.
I think the bug already existed in previous versions but after the last update it’s happening a lot more often. I’m not saying it makes a big difference if it’s old or new, I’m just pointing a few places it can be reproduced in current and previous versions, hoping it helps to find the cause.
I have an older version on Mac (High Sierra so can’t update) and the bug is there, just different spot.

Thanks.
Apparently it doesn’t happen in London (or it’s less noticeable).
Pretty certain it does. As you say, it’s just more noticeable in some areas - particularly where there’s a lot of foliage casting various shadows. A lot of London is built up.
Bug still present in update 1.31. In the first KM of Yorkshire UCI circuit it flashes like 10 times.

Particularly obnoxious on France, due to it being permanently bright sunlight.

This one seems to be fixed. At least in the first km of Yorkshire where it used to happen various times before the update.
We’re supposed to just find out for ourselves I guess. But yeah, on a quick test there was a bit on Watopia where I could trigger it every time that seems to not be doing it any more. Hopefully resolved.
