With HDR making its debut on Plasma, what are the plans moving forward?
From what I have seen getting games to work in HDR currently requires the correct vulkan layers and a recent gamescope version?
As a side question, will there be an easy way to get HDR working with the Steam flatpak for the Plasma 6 launch?
A near term plan is to make it so you don't have to use any Vulkan layer to make it work, by having gamescope use the protocol directly. After that, add support to all the other clients - Mesa, SDL, glfw, mpv, Krita, Chromium and so on
You can run Steam in gamescope, doesn't matter if it's sandboxed or not.
Thanks for the response, excited to see more support being added!
So, installing your Vulkan layers and gamescope-git on the host and running
ENABLE_HDR_WSI=1 gamescope --hdr-enabled --hdr-debug-force-output --steam -- env ENABLE_GAMESCOPE_WSI=1 DXVK_HDR=1 DISABLE_HDR_WSI=1 flatpak run com.valvesoftware.Steam -bigpicture
should do it on Plasma 6?Yes
