Ah, you are right, I installed Element from the Google store (using Aurora).

But Mastodon is from F-Droid and it uses Google notification service, I just checked.

I think Mastodon and Element use Google’s push notification service.

I have microG installed, and both apps show up as registered for cloud messaging.

Same problem 😢 Will play in MPV in the meantime. Luckily, there aren’t many HDR videos on YouTube.

BTW, if you aren’t on Nvidia, you can remove ENABLE_HDR_WSI=1. It’s for https://github.com/Zamundaaa/VK_hdr_layer which is not needed if you have recent Mesa drivers.

Thanks for the help!

Strange that enabling hdr on a clean profile doesn’t work for me 🤔

Maybe it’s because I use Nvidia. I regret this choice every day.

Yep, it works in Chromium. And I checked media.prefer-non-ffvpx just in case.

I’m glad it worked :)

As for Firefox, a new profile was the first thing I tried, but I always get the same result… What did you change in the new profile to make it work?

I just managed to get Cyberpunk with HDR working. I downloaded Protonup-Qt, installed GE-Proton10-25, selected it in Steam and added PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 ENABLE_HDR_WSI=1

I downloaded firefox 144

Hmm… It’s still washed out for me If I downgrade it.

Ah, got it! Yes, HDR works fine for me in MPV. Maybe I should install an extension to open videos in it 🤔

I’m also on Plasma 6.5 and I set HDR to enabled… So you didn’t enable the toggle in about:config? In my case it shows the video on SDR.
