I have some more data to report.

The issue also occurs for me on Microsoft Edge on Windows 10 x64
The issue does not occur for me with Google Chrome on Windows 10 x64
The issue does not occur for me on Microsoft Edge through a fresh Hyper-V VM for Windows 11

I have tried disabling all extensions (ublock origin and bitwarden) and loading the page as well as a full cache clean to no avail.

My primary computer that I'm reporting the issue through is Windows 10 x64 - latest updates - and my color settings are as follows (although I've obviously tried setting Light Mode, but tried messing with app/window mode default to see if that might trigger something - nada)

Thank you for posting a working image, clearly there is something more going on than meets the eye

Update - I did some Googling and came across this:

Firefox - Website appearance set to Dark - about:preferences#searchResults

Edge - https://www.reddit.com/r/MicrosoftEdge/comments/1ayyiu6/stuck_in_dark_mode_how_do_i_turn_it_off/ - edge://settings/?search=dark

I can confirm that setting either of these options to System Default/Automatic will "fix" this or work as expected, but hear me out as I still believe there is an issue here.

I think this is still a bug though, because I would expect Argon/LuCI to be able to override this through the configuration, and it doesn't seem possible. I've never really encountered a situation like this before, but I'm happy I found out what's causing it now.

Hello - I just wanted to bump and check in on this issue - installing latest on 23.05.4 seems to still have the same issue as described above and just making it known that the issue still exists.
