I created a project to get a screenshot with transparent background, it works on ios13 14, Android and pc browsers.
But on the iPhone12 Promax ios15.0 and iPhone13 ios15.0, i got a fuchsia background.
Does anyone know how to fix the bug? Many thanks！
This is the link of the project: PlayCanvas 3D HTML5 Game Engine
@koolou The project works for me on iOS 15. The screenshot is transparent when I press the button.
Have you fixed the project?
Interesting that it doesn’t look like that on my iPhone 8 with iOS 15 
I added a png image mask 
but it only works under a certain angle
maybe u need a new iPhone 
Cannot reproduce on iPhone XR with iOS 15 either.
try to open in iPhone12 13 ？
Sorry, we don’t have access to those phones with iOS 15 
I now have a device (iPhone 12/13 Max Pro) that can repro this issue
I take that back, I can only reproduce this in the published build above linked above. I cannot reproduce this in a new project: https://playcanvas.com/project/940813/overview/f-test_1
