Nixpkgs: Zulip opens blank

[laMudri]

Describe the bug
When opening Zulip on recent nixos-unstable, the application starts, but the only display is a completely grey window. Things were fine a couple of weeks ago – for example at commit 1e3f09feaa5667be4ed6eca96a984b4642420b83. This is probably an Electron problem, though most other Electron applications still work on my machine.

To Reproduce
Steps to reproduce the behavior:

1. Install zulip from nixpkgs at commit 61525137fd1002f6f2a5eb0ea27d480713362cd5.
2. Run zulip.

Expected behavior
Graphical application opens with channels and messages visible.

Thanks. I've pulled nixpkgs master at 558303ba076e4affcc52a7d2f7d57308b29520f2 where it's merged and it worked great.
