Hello
Since last update via zypper dup on 2022-09-25 I have a problem when playing videos in firefox: They are shown in various shades of grays then browns or reds
This occurs for streaming video and local mp4 file. see screen shot: https://paste.opensuse.org/images/65131162.png
In vlc the local mp4 file is correctly displayed in color.

Some streaming videos start with pink shades

Mozilla firefox version
Code:
hpprol2:~ # rpm -qa MozillaFire*
MozillaFirefox-branding-openSUSE-68-3.5.x86_64
MozillaFirefox-104.0.2-2.1.x86_64
I tried with a new user and the same problem occurs

In the history log of zypper I see that the last update for firefox is on
Code:
cut -d "|" -f 1-4 -s --output-delimiter " | " /var/log/zypp/history | grep  "irefox"
...
2022-09-12 07:59:56 | install | MozillaFirefox | 104.0.2-2.1
But I'm sure that the videos were correclty displayed after that
So it must be a library used by Firefox that has changed
Any idea from where this problem is coming?

Philippe
