Stable version (5.2.1168.74)

But this didn't have to be done on the previous stable version. Is this again the Google "feature", for which you need to turn on this flag on new versions?

What version of Windows and what version of browser x64 or x86?
it's just that dark pages work fine for me on windows 10 (19045.3208) x64 browser https://qu.ax/pgPJM.gif other error pages also seem dark.
Do you have any white error page or just the one on the screenshot? Try chrome://kill/ if it's also white, then maybe there's a bug with Windows or the browser version or profile. Try it on a clean profile too.
there was a message about the dark theme not working for websites https://www.centbrowser.net/en/showthrea...0#pid28000 but not about browser pages
so far there has been no one else who has confirmed this error (I'm talking about browser pages)
