@MetalAnon
Hi, could you tell us what iOS version and what Apple device you are using? Does the error happen every time you open radar layer? Does it also happen on the satellite layer?Thank you!
-
@schilpat iOS 18.7.2, pushed last night apparently. iPhone 13 Pro. All updated to latest.
Clicking on satellite does something strange…
Adding the following error to the log…

Also confirmed on iPhone 13 mini running iOS 18.7.2 RC (22H123)
Same behaviour in both Windy app v47.010417 & v47.020121 -

@MetalAnon Hi, since the error appeared after updating the iOS version, and the version 18.7.2 (RC) is not a stable version, there is a high chance that something related to WebGL got messed up by Apple in that version. We cannot do much about it :/ We always recommend using stable OS versions to prevent these problems.
-
Have filed feedback (FB20873873) with Apple in relation to this issue. If possible I'd suggest others do the same.

I was afraid that’s where we end up. Thank you for checking that. I’ll see what I can do about filing bug with Apple and thank you to the other two participated in this thread much obliged. Have a good day.
-
Hey, I’m having trouble finding the proper page to post Apple feedback for this problem. You have a link to your feedback?? Thanks!

@MetalAnon
It is an Apple pre load app. I tried to share it here but it wouldn’t copy and I couldn’t find it in the App Store. Try this link https://feedbackassistant.apple.com/ -
Apple appears to have fixed the WebGL issue in a new build of 18.7.2 (22H124) which has now been publicly released.
NB you may need to reset iOS Beta Updates to Off to make the updated release visible
