What happens in X11? What OS? What Desktop? Did you try with Firefox in Troubleshoot Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode Try downloading Firefox from Mozilla. Download, unzip, and run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

Hi.

My understanding is HDR can only be enabled in Wayland

OS/Desktop was mentioned in Subject - Linux / Plasma 6.4/Wayland

I will try downloading the binary mentioned and running in troubleshoot mode - but given that other link i posted this seems to effect users regardless of which distro.

I will update later - thanks

Duh... you did mention Plasma.  ;-)) Wayland issue... Jones out...

The binary build of firefox did the same.

However ... I have found that this only effects when not viewing full screen

i.e full screen SDR content (when HDR is enabled) is ok also if you 'pop out/Picture-in-Picture' the video .

Really odd

This is a work-in-progress. It still has many bugs. There's a reason it's not enabled by default.
