Red tint with nVidia proprietary drivers
Affected version
Dell Precision 5520 Hybrid Laptop 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 630 (rev 04) 01:00.0 3D controller: NVIDIA Corporation GM107GLM [Quadro M1200 Mobile] (rev a2)
Running Arch Linux with: nvidia 510.54-3 mutter 41.4-1
It seems similar to gnome-shell#4071, but happens here on Wayland also!
Bug summary
On BOTH Wayland and Mutter the display has a red tint. This is only the case on the internal screen, not on an external screen. The issue is not visible on screenshots.
When switching terminals (From Term 2 where Gnome-Shell is running to term 1 where GDM runs and back) the issue is resolved. So it seems like switching terminals triggers something that fixes is.
Also it seems unrelated to night-light, as disabling it has no effect. And when night-light is force activated, it gives different colors.
Steps to reproduce
Reboot Login to Gnome Wayland or X11
