Using SDK v5.2.42043.1112 I had implemented annotation support with a custom UI. It uses a system overlay to place a MobileRTCShareView on top of the whole OS and this is where the drawings are rendered. Everything was working great.
Then I attempted to upgrade to SDK v126.96.36.1997 and I noticed that the system overlay had become solid black, blocking your view from the entire OS. The annotation drawings were still rendering however, you just can’t see the underlying Zoom app or OS.
I tried explicitly setting the background color on the MobileRTCShareView to be Color.TRANSPARENT, but that did not help. There’s no other views or view groups involved, I add the MobileRTCShareView directly to the window manager.
This is also a problem in SDK v188.8.131.523. Last known version it was working correctly was v5.2.42043.1112.
