window.zoomLevel causes font's to shift up or down

[drewhamlett]

I've narrowed this down to the zoomLevel setting. It doesn't happen if it's not set.

• VSCode Version: 1.31.0-insider (and stable)
• OS Version: MacOS 10.14.2

Steps to Reproduce:

1. Set "window.zoomLevel": 1 (to increase sidebar size)
2. Scroll down then back up
3. Delete a line
4. Random lines will shift up or down

Does this issue occur when all extensions are disabled?: Yes

I pulled down master of vscode and ran it locally. It seems setting the css property zoom, or transform to zoom the editor makes this go away. Everything in the editor is based off the window zoom level so it messes up a lot of things. Might be helpful

Just a heads up. I can't reproduce this in the exploration build with Electron 4. So it happens in Electron 2 and 3.

Version 1.31.0-exploration (1.31.0-exploration)

Since we now ship with Electron 4.x, this must be fixed...

Yes, not seeing this anymore. Thanks!
