Bug ID: 495869
Summary: There is a color mismatch on application's text being
rendered when I enable HDR on my monitor (AW3423DW) as
I am using an NVIDIA card
Classification: Plasma
Product: kwin
Version: 6.2.3
Platform: Arch Linux

Color mismatch when opening firefox and see the color mismatch in the bookmarks
SUMMARY: When I enable HDR option on my monitor(AW3423DW) under Wayland with my
NVIDIA card by adding KWIN_DRM_ALLOW_NVIDIA_COLORSPACE=1 in /etc/environment.
When I tick the enable HDR option, applications couldn't render with correct
colors as I would see some color mixes when I move applications to certain
places on my monitor(most noticeable under konsole and firefox). Although the
method can solve this issue, I can still see color mismatch but less
noticeable. The latest NVIDIA driver I have for this issue is 565. This problem
still persists in Plasma 6.2.2 but the black screen when leaving hdr enabled
when login into Wayland is fixed after upgrading to 565. I have reported this
to NVIDIA developers but they haven't
responded(https://forums.developer.nvidia.com/t/565-release-feedback-discussion/310777/113)
STEPS TO REPRODUCE
1. Add KWIN_DRM_ALLOW_NVIDIA_COLORSPACE=1 in /etc/environment
2. Enable HDR
3. Open applications under Plasma like Konsole and Firefox ( See the bookmarks
for the effect)
OBSERVED RESULT
Texts in the applications like Konsole and Firefox would have mixed colors when
moving ( can be seen even without moving)
EXPECTED RESULT
Applications under Plasma should have their color be consistent regardless of
where it was moved
