When using FF and typically Netflix, in scenes of movement, there are artifacts around the moving sections like horizontal raindrops, very thin. Static scenes are fine.

Ive tried no acceleration/recommended and other settings, started in safe mode, correct Plugins are installed, sudo apt install libavcodec-extra, but the issue does not change. No such issue in Chrome or ElectronPlayer.

Hardware is a Lenovo E590 Thinkpad, but clearly its not a hardware issue as it only appears in Firefox. Any ideas? Thanks, Al.

Hi,

this is a known issue and it's fixed in version 76.

This seems to be a slightly different issue than OP in bugzilla as its not a single line, but a screen full of raindrops. Oddly, when doing a screencapture, the artifacts do not show, only the live screen shows.

I do not have FF V76 to confirm its fixed.

You can try to enable WebRender, via either of these prefs:

  • gfx.webrender.enabled = false
  • gfx.webrender.force-disabled = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Thanks; but no difference I had tried other configs as well but no change.
