Fluxer looks extremely saturated with HDR enabled

(#431) Bug Fixed desktop packaging
by RexSystem edited originally by @pollux78 on GitHub

Summary

I noticed that when i enable HDR on my monitor in KDE Plasma on linux it looks extremely saturated, weirdly tho it only shows on a monitor that is not using HDR, and when i disable HDR on the monitor it then shows it aswell until i relaunch the application. The question is. Is this a upstream issue or a fluxer problem directly?

Steps to reproduce

  1. Enable HDR on the monitor in KDE Plasma
  2. Notice Fluxer looks ok on the monitor with HDR enabled
  3. Notice Fluxer does not look ok on a different monitor without HDR enabled on it
  4. Notice when you disable HDR fluxer will look not ok aswell on the SDR monitor.

Environment (optional)

Flatpak Fluxer stable build 87 2026-03-11 Electron 40.0.0 desktop stable 0.0.0 CachyOS

Logs or screenshots (optional)

HDR disabled image HDR Enabled brought over to a second monitor + if you turn HDR off it also will show this saturated experience image

I've recorded this behavior here. The left monitor is HDR, the right monitor is standard. They are also different resolutions, which explains the size difference. In this recording I have both the flatpak and the appimage installed. The flatpak, when dragged between monitors, changes its color profile and permanently becomes oversaturated when viewed on the non-HDR monitor if at any point it is dragged to the HDR monitor, until next launch. When the flatpak window is moved back to the non-HDR screen, the terminal outputs the following:

The appimage does not have this problem. 567373510-1b9146e5-1e87-4236-913e-cce7be4cb7eb.mp4 For completion, my system is running Bazzite with KDE Plasma.
