The dark theme is nice, but all scrollbars are still light, and so is the window title bar. The scrollbars especially are very eye-catching and distracting. Naturally the lightest and most high-contrast elements stand out most - it's like the scrollbars were the most important thing and in comparison everything else recedes to the background.
For examples of what I think it should look like, try Visual Studio or JetBrains Rider in dark mode.
(On Windows, and yes, I have set Windows to dark mode.)
