Cannot share game without sound after latest update in a DM

In the new interface, there is no way of turning off sound if I share a game window in a DM. I can either:

1) Share a game window. Sharing the game's audio.
2) Share my screen. Without sharing any audio.

Before this update, I could:

1) Share a game window. Sharing the game's audio.
1b) Share a game window. Without sharing any audio.
2) Share my screen. Without sharing any audio.

If me and a friend are both playing a game each and don't want to bother the other person's experience with audio, but allow our friend to look at what we're doing in a game, this should be possible. It used to be.

The only workaround right now is sharing the entire screen and I should not have to go into any detail why it isn't great that a friend can always see what's happening on my main monitor. All my notifications, every pop up window, everything that's there when I alt-tab, etc. It's a huge privacy issue.
