Playback clips backwards and timer keeps rolling

[repomansez]

Describe The Bug
When I'm watching something, the video clips backwards a couple of seconds, and it isn't reflected on the timer. Once it happens, it happens every single time in the same exact spot, until playback is stopped (e.g refreshing the tab), and then it's gone.

It does not happen when reproducing the same file with a local media player.

Steps To Reproduce

1. Play anything
2. Wait (I'm unfortunately not able to figure out any way to reproduce the bug consistently, it happens intermittently)
