Upgraded from 1.17 to 1.19 and the pause button no longer pauses video when using MadVR renderer. It used to work fine. It still shows the pause symbol on the screen, and the info bar along the bottom, but the video continues playing. Switching to the EVR renderer makes the pause function work correctly again, it only seems to be a problem when using MadVR. I was using MadVR previously on 1.17 and that paused correctly.
