Description

a year ago
OS: Windows 8.1
Firefox versions tested:
- 59.0a1 (2017-11-14), 64bit
- 57.0, 64bit

Steps to reproduce:
- View a video (tested on youtube.com, vimeo.com, imgur.com, bbc.com)

Actual results:
- Distortions seeming to separate magenta and green (see screenshot)

Expected results:
- Normal colors


Other investigation:
- Restarting in safe mode *DOES* fix the problem
- The Firefox screenshot feature *DOES* show normal colors
- Using a clean profile does *NOT* change the results
- Disabling plugins Cisco OpenH264 and Widevine does *NOT* change the results

Can you try setting media.wmf.use-nv12-format to false and see if that fixes the issue?

thank you

Setting "media.windows-media-foundation.use-nv12-format" to false fixes the issue.

It has also been fixed in the latest nightly.
