Issue #1230: Latest snapshot (June 14th) makes colors washed out on my laptop
Created: 2024-06-15T03:02:30Z
Describe the bug
(Copying from the discord)
I updated today to the new snapshot and now my colors look quite washed out on my laptop display. Rolled back to the previous snapshot and everything looks normal as it always has up until this point.
What did you expect to happen?
I expected the colors to look the same as before.

The only changes I make to stock bazzite with my bluebuild image are to add vscode and mullvad vpn to the base image.
Note: This problem did not occur on my desktop, just the laptop.

Duplicate issue #1347: Weird washed out colours in GNOME affecting 1 screen in a triple monitor setup
Created: 2024-07-10T19:02:14Z
Describe the bug
Kind of hard to explain but the colours seem washed out or have too much white/grey tint. It's definitely not a brightness setting or a colour profile. It seems to only affect one of the 2 Dell monitors I have. Initially it affected my second monitor but now it's moved to the first and the second one is fine.
What did you expect to happen?
Brightness/Saturation was normal until a few weeks back

Extra information or context
I have 2 Dell G3223D Monitors and a 4K TV hooked up to my PC. I'm not sure it has anything to do with the fact that I'm running triple monitor because when I plug everything else out except the affected monitor the issue persists. Oddly, it started a couple weeks back but resolved itself after a reboot. I have updated the monitor firmware to the latest using a Windows machine.
I've tried factory resetting the monitors, deleting colour profiles, disabling VRR on the monitors, setting lower refresh rates and resolutions, nothing changes the washed out look of the image. I've even moved the affected monitor to a different port on my graphics card and it's still the same. I plugged my laptop into the affected screen and it's fine.
Any advice for debugging?

Closing comment (2024-07-11T13:21:34Z): May be related to #1230

Doubtful as that bug seemed to be related to software brightness control which my monitors don't have. Nevertheless I tried to see if I could get the output of
cat /sys/class/backlight/amdgpu_bl1/{brightness,actual_brightness}
But that didn't work because, since I don't have a software controllable backlight, there's nothing under /sys/class/backlight/

Check that you don't have HDR enabled.

Yep it's definately turned off on each monitor itself. Interestingly, I recall a few months back, HDR started "working" in the Gnome session but curiously only on one monitor. At that point I still had HDR enabled on the monitors. It didn't look very much like what I'm experiencing now but the white balance was definately way off and everything looked terrible. I tried messing with a few settings but ultimately disabled HDR on the monitors as I figured it was still early days for HDR in the Gnome session.
