White Flash in Dark Theme

[JHaller27]

Issue Type: Bug

System info:

• VS Code on WSL (though also reproduced on host Windows 10)
• System theme set to dark
• VS Code Color Theme Preference set to "Dark+ (default dark)"

Repro steps:

1. Open VS Code

Expected result:
VS Code opens in dark mode, without flashing white

Actual result:
VS Code flashes bright white before switching quickly to dark theme.

I do not have epilepsy, but this could certainly be a trigger. Even without epilepsy, it hurts my eyes and is rather frustrating. I'm no expert, but this feels like an accessibility violation.

Please update to the lastest version of VS Code and confirm the problem is still there.

@chrmarti Sorry, I was having issues updating (probably a WSL thing, not a VSCode thing). After updating my specs are:

I can also reproduce this if my VS Code was opened in full screen mode, then closed, and opened again.

I have the same issue with Dropdown Menus (File, Edit, Selection, ...). Clicking on a menu causes a white flash.

Edit: I found it's an Electron issue electron/electron#18184
Edit2: Upgrading to Electron 8.1.1 should solve this issue
