Chrome on Ubuntu desktop over RDP causes keyboard to become disabled

This one is interesting.

I have Ubuntu 19.04 installed on Hyper-V, and accessible via RDP. This works, except that when I start Chrome, the keyboard is disabled – no applications can receive keystrokes.except for password dialogs which can still read the keyboard.

As soon as I close Chrome, the keyboard becomes active again.

Weird, huh? Any ideas?
