Washed out colors only on Chromium based browsers
SUMMARY
Hello, this issue started happening around one week ago after Chromium merged
HDR support for Wayland, for me and many other people now the colors on
Chromium based browsers look completely washed out, and the only workaround for
now is to disable hardware acceleration in the settings or add this argument
"–disable-features=WaylandWpColorManagerV1 --force-color-profile=sRGB"
I've attached a screenshot of how the colors look now.
Here are some links of people experiencing this issue, and the only thing in
common between these people is that they are using KDE Plasma:
https://www.reddit.com/r/kde/comments/1nzy72u/has_anyone_else_encountered_this_problem_too/
https://community.brave.app/t/washed-out-colors-when-hardware-acceleration-is-enabled/643668
So then I got suspicious and I've tried to see if the issue was present on
other Wayland desktops, and I can confirm that on both COSMIC and GNOME I don't
have this issue, and the colors look normal even with hardware acceleration
enabled.
The interesting thing is, that I don't have any HDR capable monitors, so I'm
wondering if Chromium is thinking that my monitor is HDR and it tries to
display HDR colors, but fails because my monitor is not HDR or there is
something else going on, another option I am thinking is that maybe Plasma is
giving the wrong information to Chromium about my monitors and that's why it
thinks they're HDR capable when they're not? Idk.
The other interesting thing is that this is not GPU vendor related, people seem
to have this issue with all brands of GPUs, and only on KDE Plasma.
STEPS TO REPRODUCE
1. Use a Chromium based browser with Hardware acceleration enabled.
OBSERVED RESULT
Colors are washed out.
EXPECTED RESULT
Colors are not washed out.
SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
