Hey all - we’re investigating this symptom. Thanks for the reports.

Hi all, FYI that we are rolling back the 1.44 game release only for Windows users back to 1.43.3 while we investigate this issue further. For those of you who were affected, please let us know if this issue was mitigated after returning to the 1.43.3 game release.

Zwift v 1.44.2 should fix this issue. @Ruben_de_Miguel_de_L @Alfonso_Piza @Phil_Bradey please update at your earliest convenience.

We’d appreciate if you’d loop back and confirm / deny you’re back to normal. Thank you in advance.


I’m sorry I’m on holiday (vacation) now. I’ll not be home again until 13th August.

After uninstall and reinstall (more than one hour) it works. Thanks!

Why did it take an hour!? Does this system have a mechanical hard drive? It should not take anywhere near that long.

sounds like they had to uninstall the whole game and reinstall it, an hour still seems long but depending on internet speeds could take near that

I dont know, I will ask to my very old PC

Ask your PC if it has a mechanical hard drive. If it says yes, offer it an SSD and it will be happier. This upgrade is not expensive and it’s the #1 reason for slow performance of the game.

Yes, my very old PC has a SSD hard drive. I upgraded it to 8 GB RAM too. Next upgrade will be the microprocessor or the video card. What willl you do?

It depends on what you’ve currently got?

Of the two you’ll get more benefit upgrading your graphics card.

depends what you want to improve?

do you want it to look nicer, run smoother or both?

if you give us the full specs of your PC i’m sure someone will be able to advise on what would get you the best performance

We found this particular blacked-out image issue impacted older CPU’s that were low-spec to begin with.

Upgrading the CPU can be tricky because motherboard sockets are specific to a CPU family.
It’s also possible that your CPU is permanently soldered in place. This has been a trend in recent years for system manufacturers.

At some point it becomes more cost effective to replace the entire computer than upgrading one component at at time. If low cost is important - a recent-generation AppleTV 4k is the most cost-effective device on the market that runs Zwift.

This issue is definitely not fixed yet.
First race after the update today; and one hour in the Zwift Screen went black.
Like in the OP, data was still being submitted (visible in sauce and companion app); but even after 30 minutes the Zwift screen stayed black.

I am operating on Windows 10 as well - please contact me if I can help with logs or in another way.

Hi Chris, John with Zwift HQ here. Thanks for reporting, and I’m sorry to hear about the screen going black during a ride.

Can you confirm that the screen looks the same as in the OP, where the game itself is black but you can still see the HUD and buttons.

Also, are you seeing this on every ride after some time or is it happening immediately once you start your ride?

Hey John. For me the entire zwift screen was black, so unlike OP I hd no menu button / HuD.

But in companion app data was coming in and I could finish the race.

So far it has not happened again - the incident I had was in the 3rd lap of Chasing Rainbows, so about 1 hour into the race.
