Websites not displaying colors correctly in dark mode

[Adotiln]

On some websites, the background appears to be set to white or some other similar color, which in some cases makes text illegible. The two websites I seem to be having the most trouble with are 5etools and GitHub. Below are screenshots comparing how they currently look in Brave to how they look when I use the same websites in Firefox.

5etools in Brave:

I have tried using Brave flags and enabling “Auto Dark Mode for Web Contents” and while it somewhat fixes 5etools, GitHub stays exactly the same. I also feel like I should note that both of these websites appear as they should on my Android version of Brave, so this appears to be a problem exclusive to Desktop Brave.

Brave Version: 1.80.120 (Official Build) (64-bit)

Additional Information:
Operating System: Windows 11 Home Version 24H2

I do not have this issue here on the same version, and on the desktop. I also have not used those flags for Auto Dark Mode, and leave all flags on “Default”, and it just works.

Do you possibly have an extension installed that’s interfering? What does Private Window do?

For some reason, I did not even think about it possibly being one of my extensions and it turns out this was apparently being caused by the “Flash Player for Web” extension (The one I had isn’t available on the extension store any more). I’m not sure why that one was doing it since I’ve had it installed for a while now and this problem only popped up recently, but after disabling it, everything displays as it should. Thank you very much!
