when iOS 15 system updated, our h5 game display error

Before update the system version to iOS 15, it all works well.

error url:

https://game.ivydad.com.cn/chinese-wordL2/?nodeId=206962&env=production&source=ios&memId=2470906&color=65d1a7&hide_next_btn=0&language=chinese&autoPlay=1

Using Safiri, it couldn't show game content any more. Watch carefully, game shows at the top of the page and seems showing as a line. But after I rotate the iPhone device and rotate back, it turns OK.

The operation video url:

https://game.ivydad.com/temp/normal_video.mp4

We have tried to redispatch event "resize" or modify the canvas style such as left top, error still exists.

How can we solve this? Begger for helps.

It's a game engine adapter problem, fixed by engine developer. So it can be closed.
