Vivaldi browswer with CSD.

When turning off native window title bar, the shadow is not present in all Chromium based browsers (Vivaldi, Chromium, Brave, etc.)

STEPS TO REPRODUCE
1. Launch the browser (in my case Vivaldi)
2. Remove native window decoration, use CSD

OBSERVED RESULT
No shadow around the active window.

EXPECTED RESULT
Shadow around the active window.

SOFTWARE/OS VERSIONS

Actually I'm starting to wonder if this is Chromium's fault. Does it in fact define its own shadows when using CSDs?

Kai, do you know?

It is Chrome's fault
Comment 3 Nate Graham 2020-02-16 16:30:40 UTC 
Thanks, I suspected as much.

Mohan, can you file a bug on Chrome/Chromium requesting that the app draw shadows when using client-side decorations?
