Fedora 40 update - (in wayland) - has created dull brightness & contrast

Hi there,
I just updated Fedora 40 - (using wayland). I’m using an AMD GPU. Following this update I now have washed out colours and reduced brightness and contrast.
I have checked this isn’t the case with a different boot distro. I have also checked power management brightness settings but this isn’t the cause.
This is obviously a bug. Any solutions ?
Thanks
Rab.

OK…I have found the solution. Go to power management and increase brightness to maximum and then select: Never…for brightness dimming. Click apply and fully vibrancy is restored :slight_smile:
