Content is overflowing corner masking & shadow

I'm running the first El Capitan public beta. While corner rendering issues pre-date El Capitan, its exacerbated on this new beta.

Window content overflows the the border radius of an otherwise rounded border and shadow.

Some additional screenshots taken on a 1x display when the content isn't overflowing:

Native window (smooth, anti-aliased)

Electron

Here's a zoomed in version of each focusing on the same corner.

Is it possibly related to Chromium issue 396264? The solution there is compiling Chromium with 10.9 SDK, so people have to wait until Chromium drops 10.8 support. Currently libchromiumcontent is also compiled against 10.8 SDK.

The corners problem of window on Mac have haunted me since the first days of electron.
