iOS 17 render problem

[bjorn.syse]

Hi there

We just noticed a problem viewing one of our projects on iOS17: www.worldofepiroc.com. Looks odd (silver) in both chrome and Safari on iOS 17.0 but fine on chrome in windows.

What could be happening here?

Issue (Safari iOS 17):

Expectation (Chrome Windows 10)

Basis tend to randomly fail to transcode on iOS17, see more here

Basis Failed to Transcode on iOS 17

I have a site that has been live and running fine for the last 11 days: Built, tested, and running perfectly on PC, Mac, iOS, Android. I have an older iPhone 11 and today I upgraded to iOS 17. Now my site will not load on my phone and the errors are basis files failing to transcode (both chrome and safari) Tried running out of the editor and I get the same issue. Using engine ver 1.65.3 Is there a newer version I can be using? Please help as 90% of our traffic is mobile and more than half …

We’re investigating possible workarounds.

Hi @bjorn.syse,

We have a PR to fix this Handle ios 17 basis wasm regression by slimbuck · Pull Request #5657 · playcanvas/engine · GitHub. If you’re able to test with this fix locally and confirm it works on all your assets, it would be much appreciated.

Thanks!

Thanks, sounds promising. Won’t have time in a while to test it though unfortunately.

The fix / workaround: Release v1.65.5 · playcanvas/engine · GitHub

Hi, I dont see 1.65.5 in my editor ‘Engine Version’ dropdown. Do I need to do something?

[mvaligursky]

So far only tje engine has been release, and should be promoted to the Editor tomorrow.

Hi. It seems latest version of iOS has this problem fixed too.
