When atomically setting gamma ramps on AMDGPU (specifically ),=
 the changes
don't take effect until switching to another TTY and back again. Using the
legacy DRM interface works as expected.

To reproduce, build and run the rootston Wayland compositor:

https://github.com/swaywm/wlr=
oots

We will shortly be merging this patch for a new gamma control protocol
extension, which you will need to apply if we haven't merged it by the time=
 you
attempt it:

https://github.com/=
swaywm/wlroots/pull/1157

An sample program will be available in the build directory,
./examples/gamma-control, which can adjust gamma. By default this will use =
the
atomic interface, set WLR_DRM_NO_ATOMIC=3D1 before starting rootston to use=
 the
legacy interface. Our atomic gamma code is here:
