Flashing Roads on Neokyo World


Since the last update I have noticed roads flashing colors on about 1km of roads at Neokyo. It happens as you approach the blue arch after the arcade. Sometimes is quite frequent and other times just a few flashes. I am using appleTV with latest updates. I heard another rider mention it on a group ride last week. It happens so fast that I cannot get a screen shot.


I saw something along those lines in Neokyo myself recently, although I can’t remember where it was exactly (but my route did include the arcade). As you say, very hard to get a screenshot.

I’m on AppleTV too.

Hi @the_guaiwu and @Steve_Hammatt,

Thank you for reporting this, and I’m sorry that you’re experiencing this.

When the road flashes, does the road disappear and you can see underneath the road then the road reappears, or is the road still there and something is flashing where the road is suppose to be?

I don’t believe you can see through the roads. The roads flash bright red, green, blue, orange… I have seen it on four different rides. Last Thursday it was quite brilliant and the game on the appletv locked. The screen froze and the remote seemed to not control the appletv. I was still in game and could follow the ride on the map page of the companion app. After 5km I saved off of the CA and rebooted the appletv and it worked fine. I still had the flashing roads though it did not lock the appletv again. Next time I can go to Makuri I will try to video with my phone and attach.

Thank you for that detailed description @the_guaiwu, and I appreciate your offer to record the video as that would be helpful.

If you are able to record a video of the roads flashing bright colors, please reach out to our support team with the video attachment mentioning your forum post so we can troubleshoot this further.

If you haven’t already done so, I’d recommend reinstalling Zwift to see if it resolves the issue. To do that, just follow these steps:

  1. On your Apple TV home screen, select the Zwift app.
  2. Press and hold the clickpad center or touch surface of your remote until the app begins to move.
  3. When prompted, press the Play/Pause button on your remote.
  4. Select Delete twice to remove the app.
  5. Turn off your Apple TV. and Unplug the power from your Apple TV for at least three minutes.
  6. If at least three minutes have passed, plug the power back into your AppleTV.
  7. Re-install Zwift through the App Store.

Hey Sam, here are 5 pics I took at the start of the SCZL ride yesterday, 9/1/2022 @ 3:10pm PT. This issue started after last big release, got somewhat better, then this happened yesterday. Note this also happened last week on a group ride on RGV, but I was able to continue/complete the ride as the effect only occurred in a few places and was short lived, but just as intense; need to look away or I will get a bad migraine. I can provide specific details about the macbook/OS I’d you’d like. Thanks for your efforts. It’s frustrating to have to bail on your fav groups/rides.

Hello Sam,

I sent a short video to the tech support team. I then deleted and reinstalled Zwift on the AppleTV per below instructions. This morning in Neokyo I still see some of the flashing roads fairly consistent in locations on the route. Not nearly as intense as what Jim posted below. Next I will try a different HDMI cable to eliminate that as a possible cause. Have a great Labor Day weekend.

Same here on Bacon Rolls this morning.

Started with C grade and 200+ riders and it was unrideable…screen display flashing 95% of the time.

Switched to D grade with ~70riders and much better…intermittent flashing near the arcade each lap but otherwise ok.

Btw this flashing in Neokyo has been occurring for weeks, but todays was the worst ive seen by far.

Mac OSX.

Screenshots attached.

Yikes. Surely related to the Metal switchover.
