Hello all,

I’m aware that this issue is ongoing for some, but not all Zwifters with AMD graphics cards. I’ve updated our development ticket.

I’m now using a 6800 XT and this line follows me everywhere too. :pensive: Driver version 22.11.2

Here are some examples. See how it got bigger in the first picture. It has some black dots in it and it’s really annoying.

So, this bug from 2020 is not fixed in Game Update 1.33 of January 2023 ?

I had an old driver on my machine - updated it a couple months ago and then noticed this issue. Not sure what version the old driver was, but it is annoying now. AMD 5 5600/RX580 - Win 10

Another zwift fail in the making.

I’ve gone through too many its your driver issue problems only for things to miraculously fix themselves on the next zwift update. I am now getting this problem since the last zwift update and my graphics drivers have not updated in months and it worked fine before the last update.

when will zwift prorize stability? I turned zwift off for few months last year and it looks like I am going to be doing the same again, tired of issues.

New season ahead, quite a few updates since… What is the status?

Thank you!

Hi all,

It looks like this issue is still open for some Zwifters. If you wouldn’t mind sharing a screentshot of what the issue looks like for you, along with your GPU model and driver, that would be helpful for further investigation.

This is not occurring for all Zwifters with AMD graphics, but it may be occurring for more Zwifters than are writing in. Thank you all for keeping up on this

I checked on my Mac Pro 7,1 (16 core Xeon W3245) using Radeon Pro W6800X 32GB MPX Module, I couldn’t see the above issues through Tempus Fugit. This machine uses Sonoma 14.1.

My other Mac Pro (2010 model) is using RX6600XT Radeon 8GB and also works without the above issues. This older machine is on Monterey 12.7

Zwift devs somehow managed to bring back this fixed bug with the last update (1.65).

I had it the last time it was around for several years, but I haven’t noticed it since the update. Hopefully, it’s not affecting my machine this time around and it’s not that I just haven’t noticed it because my mind got so used to it.

Here a few photos, line moves as you ride along, very distracting.
RX6800XT, latest drivers
Was not there before update to 1.65

To me this doesn’t look exactly like the previous bug. Something related to shadows? Was it just like this for anyone who experienced it in the past?

Hi folks, this may not be the exact same issue as before, but it’s probably best to track the most recent occurrences in this thread here. @Jon_M_TBR , did you happen to catch any screenshots of this occurring in 1.64.0?

Sorry, meant was not there before 1.65 update

Never had this in version 1.64
