Streaming to discord and tabbing out and back in causes white to take over menu screen

**
I was streaming Minecraft to a friend on discord and tabbed out of Minecraft and was expecting it to be normal when i tabbed back .

But when i tabbed back in the "Minecraft" text was a white box, i thought it was funny so i tabbed back out and repeated the process. This time some of the sky box on the menu panorama was white, once again i thought it was funny, so i did it again and everything went white. After I finished laughing with my friend i loaded into a single player world, but the game crashed.

Steps to Reproduce:
1. Get into a Discord call with someone
2. Click the share screen button and select "Stream Minecraft"
3. Tab in and out of the game
