Description

after HDR mode was enabled in fullscreen by something like gamescope, when hyprland disables HDR upon switching to a different virtual desktop or quitting the HDR app, all colors are washed out until hyprland does a reload.

making any change in any hyprland config which causes the screen to reset sorts out the problem, doesn't have to be one of the experimental HDR options, but I have been toggling wide_color_gamut to fix this.

this is likely some kind of interaction between my monitor and hyprland, I have a Dell Inc. AW3225QF 97H0YZ3. there's other reported issues about various monitors not resetting after HDR mode properly, so it's possible that after returning from HDR hyprland just needs to call a screen reset to sort things out, at least until hyprland does full SDR compositing in a permanent HDR mode, like Windows does to presumably avoid similar issues.

How to reproduce

1. start anything in gamescope fullscreen.
2. watch hyprland switch to hdr mode.
3. close gamescope app, or switch to a different virtual desktop.
4. watch hyprland switch back to SDR mode, but leave all colours washed out, including blacks being obviously dark grey instead of black.

note that toggling experimental { hdr = true } on and off also causes the issue to happen, so it seems to be some issue when HDR mode is disabled, regardless of trigger.

note that a screenshot shows nothing, because the framebuffer is correct, this is an HDR/SDR display issue.

Might be an issue with mirror. Does this happen when only single monitor is enabled?
Does this happen with wide_color_gamut = 0? It is automated now, no need to enable it manually.

Need some logs with HYPRLAND_TRACE=1 AQ_TRACE=1

[nergdron]

Aha! removing wide_color_gamut = 1 from the config, and now it works correctly. so I guess whatever the automated code is doing fixes this issue. I've noticed it takes slightly longer to switch between an HDR virtual desktop and a non-HDR one, but that seems to be because it's correctly resetting the HDR settings on switch now, which is exactly what I wanted!

I have the same issue.

Dual monitor (well, laptop and external). Laptop doesn't support HDR, external does.
Unfortunately removing wide_color_gamut or trying to disable it doesn't seem to work:

experimental {
  wide_color_gamut = true
}

It gives me the error that the wide_color_gamut config option doesn't exist.

Trying to enable any of the hdr monitor options (including wide) on the monitor that does support HDR still gives a washed out desktop.

Can we reopen this? I have the same issue on fedora based image wide_color_gamut doesn't exist an option as well when trying to turn it off

[ndavd]

Same thing here, that option is no longer available please reopen this

Hi guys, I've opened a discussion regarding this issue, since the option no longer exists and the issue persists: #10950.
