Anyone knows status of kwin for these protocols?

It was pushed to Plasma 6.4

A few observations.

• Thorough review on the protocol by the mutter team
• Thorough review on the mutter implementation
• Lots of CI on the mutter implementation
• Lots of testing on the mutter implementation
• Some overlap with weston

Also fast development but that is really not a quality.

But still no HDR support right?

MrCooper has been advocating for a long time that timing control in Wayland can resolve VRR fluctuations. Really looking forward to this!

The FIFO stuff isn't related to HDR at all I think.

Wrong. Initial (experimental, not accessible via UI yet) HDR support landed in mutter 47, the plan is to expose it in UI for 48.
