[Desktop] Blank Video After Switching Tabs

[irv075]

Description

When watching a video, if you switch to a different tab and then back again, no video output is displayed. The audio can be heard and the video controls (and the rest of the page) are visible as normal - only the actual video output is blank. Looks to be a re-occurrence of #9711

Steps to Reproduce

1. Open a video (YouTube/Pluralsight etc)
2. Switch to a new tab
3. Return to the video tab

Actual result:

The video output is blank, but audio can be heard and the video controls are visible as normal. Refreshing the page or choosing a different video does not always fix the problem - the video remains blank. Switching back and forth between tabs again sometimes returns the video back to normal, or opening a new tab and navigating to the video also works.

Expected result:

Video is displayed normally

Reproduces how often:

Intermittent, but usually reproducible by switching back and forth repeatedly between several tabs, remaining on each tab for a few seconds

@irv075 Can you update to our latest 1.13.86 and see if this is still reproducing for you? I just tried it now and can't reproduce what you're seeing.

I also can't reproduce this on 1.13.86 - closing issue
