Discord Screen Share Issue

Hey, so since some update I am not able to properly screen share on Discord App anymore.
So the issue is that I wanna stream music f.e. my friends on a server. In the same time I am trying to play a game in the backround but the stream is switching focus to the game? Normally it should share the window I selected tho but it doesnt. 
The second thing is that if I tab out the game the stream closes. Idk what is happening there and I havent found any solutions. 
In need of help thanks!
