Why the Apple browser refreshes the canvas is not complete, refresh a few times to restore. There is nothing wrong with Android, nor is there anything wrong with Wechat.

Why does the Apple browser display incomplete canvas as soon as it is refreshed? refresh it a few times before it can be restored. There is no problem with Android and no problem with Wechat

I first added the automatic acquisition height code, self-adaptive, the result will not work as soon as it is refreshed, as shown in the picture is only half,
then I have to write css resolution. As a result, the refresh is still different.
refresh the friend"s full-screen display several times more.
Why?
