Black Squares Game [1.40] [1.41]

I’ve been biking outside but when I returned to Zwift then sometimes there are blinking black squares all over. Most often blinking in 1 to 3 locations each time.

I downloaded Zwift again, made sure I had the latest Launcher and triple-checked that it had no further updates.

Is there a known resolution?

Which version are you on? 1.41 is presently rolling out but you may not have it yet.

I have 1.40.0 but the Launcher says that there are no updates.

Give it a few days and you’ll probably get there. Releases don’t happen all at once any more.

You should probably get the update today if you haven’t had it already.

Think this might be a different issue but thought i’d post it here. today i got black squares where dust would normally be.
Hadn’t seen this before, i’m on 1.41 (not got the update to 1.42 yet)

it got quite distracting in places!!

This seems to be the same issue; appears to not have been fixed in 1.41.

Dear Zwift Forum, today I encountered a blacked out screen instead of seeing dust when riding on the dirt sections of Volcano Flats with Yumi. Please see image. Has anyone experienced the same issue?


I am already on Zwift Version 1.42.0. and encountered the problem for the first time today Monday 12-June-2023…

Latest version zwift and windows 11 unbearable trying to ride like this. Issue came and went during ride. Connection is as usual via wifi. There have been no changes apart from the zwift updates.




Which version is this please?

Thanks, I’ve let the team know.

That’s not the latest version. We’re currently releasing 1.42 which should be available to you in the next approx 24 hours.

Black squares is known in 1.41 and hopefully fixed in 1.42 but I have seen a couple of comments from those who say they are on 1.42 still having a similar issue. I’ve made our development team aware.

ok, will update when available.
