Green band on some youtube & instagram videos. only Firefox
Vertical green band on some youtube and instagram videos suddenly appeared today. Only on Firefox other browsers ok. Other videos ok. I run Firefox quantum on Widows ten. I tried the tip to set ,,,webm.enabled to true in about:config but the green band still there.

It could be media.wmf.dxva.d3d11.enabled or something like that. They change the name all the time.

The green band likely means that the player isn't filling the space that Firefox reserves for it. Firefox creates a green window and overlays that green area with the actual player, so if you still see green then this means that something goes wrong and there is a difference between the player dimensions and the what Firefox thinks.
Are you using a High DPI display?
What is the current setting of layout.css.devPixelsPerPx on the about:config page?
Try to set layout.css.devPixelsPerPx to 1.0 (default is -1) on the about:config page. You can adjust its value in 0.1 or 0.05 steps (1.1 or 0.9). Make sure you do not go too small or to high.
I am not certain what you mean with a high dpi display. I use a HP laptop 17 ak0xx with a 1600x900 resolution display.
The vertical green band is positioned somewhat to the left of the middle of the video, and over it. So I don't think it is the kind of problem you propose. I will try to attach a snapshot.
layout.css.devPixelsPerPx = -1 (default)
thanks!
Try set media.windows-media-foundation.allow-d3d11-dxva = false and restart the browser.
Looks like https://bugzilla.mozilla.org/show_bug.cgi?id=1352016 or https://bugzilla.mozilla.org/show_bug.cgi?id=1409105 (both should be fixed).

I don't have the variable media.windows-media-foundation.allow-d3d11-dxva in my config file.
There is only: media.webvtt........ and then media.wmf......... no media.wi.......
Can I add a new variable? How?

I changed media.wmf.dxva.d3d11.enabled to false and the green band disappeared. Very greatful.
