Screenshot of PDF incorrectly rendered in greyscale
Open any PDF with coloured text and/or images, Firefox (since version 102 and currently with 102.1) renders them in greyscale. Same PDFs were correctly rendered by versions 101.x and earlier.
OS: openSUSE Tumbleweed 20220714
Desktop: GNOME 42.3 on Xorg/Wayland
For example, see attached screenshot for rendering of Ffx (left) vs Evince (right) of the same PDF from:
Happy to help with any additional info if/as directed.
Cannot reproduce with Firefox 104.0 in Tumbleweed. (Soon to be released in TW)
I haven't checked older versions though. And I don't have wayland so if it still is a problem for you with that version, please reopen.
Just for completeness, I think this was: https://bugzilla.mozilla.org/show_bug.cgi?id=1777895
and should be fixed with FF 104+ (the described workaround solved it for me on FF 103)
