Plasma 6: How to use HDR with games? (lemmy.world)

As the title asks, how does one actually use HDR for games after upgrading to Plasma 6?

This was the feature I was most excited about, and I can hit the HDR button on my display configuration and it looks like the desktop is going into HDR mode, but so far I have had zero luck enabling the HDR feature in games. Every game I've tried had the HDR toggle disabled with no way to enable it.

I am running these games under Proton and I've tried both 8-GE and 9 Beta. Any tips?

Edit: probably important to note that I am using an AMD GPU under Wayland

This only lets you enable hdr in game. Since proton runs under xwayland the hdr info won't reach the compositor.

Oh really? That sucks, how do you work around that?

Use Gamescope and a Vulkan layer. Here's a more detailed post: https://planet.kde.org/xavers-blog-2023-12-18-an-update-on-hdr-and-color-management-in-kwin/

If you get the latest gamescope from git. You no longer need the vulkan layer.
