@r2d2292 are you zoomed in in VSCode?

[yoyo837]

Whether zoomed or not, it's the same.

Is there any solution to this issue?

[roblourens]

I see this on every window

@roblourens could you check another Electron 2 app (https://github.com/electron/electron-quick-start)?

[roblourens]

Sorry I mean every window on MacOS. It's definitely just an annoying quirk of the dark theme.

[roblourens]

Actually, it's not quite the same in other apps. I see the same issue on Chrome, Slack, OneNote, Teams, Atom, at least.

Not on Finder, Spotify, System Preferences, or apps with a native title bar.

So this appears to add support for dark mode on Mojave. But now this adds a dark line for our light themes (bug?):
