After upgrading to Kubuntu 25.10 I found that Chrome Version 142.0.7444.59 (Official Build) (64-bit), installed using the Chrome apt repo, was not as bright as it should be. I have HDR enabled and calibrated on Plasma, and would like to keep it that way.
I found a workaround from a chatbot:
cp /usr/share/applications/google-chrome.desktop ~/.local/share/applications/
sed -i -r "s/google-chrome-stable/google-chrome-stable --enable-features=UseOzonePlatform --ozone-platform=x11/g" ~/.local/share/applications/google-chrome.desktop
Unfortunately this kills the ability of Chrome to play HDR videos, which I was looking forward to. But I guess an HDR video isn't much fun if the maximum white is still grey.
This is using an AMD Radeon 780M Graphics integrated graphics card.
If this ever gets fixed in Chrome, where I assume the problem lies, then the desktop override will need to be deleted again to take advantage of the change...
rm -f ~/.local/share/applications/google-chrome.desktop
