Blender HDR and the reference white issue
blog.sebastianwick.net
The latest alpha of the upcoming Blender 5.0 release comes with High Dynamic Range (HDR) support for Linux on Wayland which will, if everything works out, make it into the final Blender 5.0 release on October 1, 2025. The post on the developer forum comes with instructions on how to enable the experimental support and how to test it. If you are using Fedora Workstation 42, which ships GNOME version 48, everything is already included to run Blender with HDR. All that is required is an HDR compatible display and graphics driver, and turning on HDR in the Display Settings.

Blender is getting HDR on Linux via Wayland before Windows! This isn’t by accident, but shows how creating a system with a different design creates better results for users and application developers.

Firefox is in this same boat too. It will get HDR support on Linux* sooner than Windows. Firefox currently only supports HDR on MacOS.
