Hello @z l,
Thank you for taking time to post this issue in Microsoft Q&A forum.
Mine(VS 2022 v17.11.5) is like this:
The Options window is still light in Dark theme.
Tested in VS 2019 as well, the same result. I have submitted a ticket on our Developer Community, here's the ticket link: The Options window and some other windows in VS 2022(17.11.5) are still light, after I change to use Dark theme, please kindly check it and follow that ticket, if there's any update, I will inform you.
BTW, it seems that there's a similar thread: Consistent Application Theme - Save Our Eyes! (A Cry For Help) which is under review.
Best Regards,
Tianyu
