Problems with screen share

[Dealum]

I have multiple problems with screen sharing on Zoom which started yesterday. 

1. When I try to share a window, it shows Zoom call participants and Zoom buttons as black boxes for the other person in the call. Moreover, if I temporarily open another window that I'm not sharing (e.g. to check my notes), my entire screen will turn black on the screen share. 

2. When I share my entire screen things work more properly but still cannot get rid of Zoom buttons and items being displayed as black boxes for others.
