Angled ‘Refracting’ line on the road | AMD Graphics [October 2022]

About a month ago I started seeing a permanent line about a bike length in front of me on Zwift that appears to be some sort of light refraction. It generally appears as a black line and it ‘swings’ around on the road depending on the angle to the light source you seem to be at. It alternates betwe…

If there are scarecrows and flying monkeys, it may be another issue.

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

Yes the new pixel bar is still visible. Did sort of chase after it which helped a bit with the TT I was doing. Noticed it dissapered over the bridges and was most visible on the tarmac rather than gravel sections.

Hi, Zwifters! I do appreciate the screenshots provided. For everyone encountering this issue, could you please share your computer’s GPU model and driver?

In case you are not familiar with Macintosh, users have no control over their graphics driver version on this platform. All that matters is the OS version and the GPU.

MacBook Pro (Retina, 13", early 2013)

OS: Mojave v10.14.6

Processor: 3GHz Intel Core i7
Memory: 8Gb 1600Mhz DDR3

Graphics: Intel HD Graphics 4000 1536Mb
– resolution 2560x1600
– device id 0x0166
– revision id 0x0009

Issue appears regardless of the selected game resolution, even at Low 576p. I normally run Medium 720p without issue.

OS upgrade to Catalina 10.15.7 is available, but I’d rather not do so if I don’t have to.
