Description

Atom is slow on certain machines/OSes with Electron 6. (Workaround: Run atom with --disable-gpu).

Steps to Reproduce

1. Have certain hardware? (I suspect this is limited to machines with no dedicated GPU)
2. Run Linux
3. Try to run Atom with Electron 6 (See ⬆️ Electron@6.1.12 #20764)

Expected behavior:

Atom should be reasonably responsive. CPU cores should all be at less than 100% usage when not doing anything in the app.

Actual behavior:

GPU process is very busy, maxing out one of my CPU cores most of the time. UI is not very responsive, taking multiple seconds to do things like draw the close button on tabs.

Reproduces how often:

• 100% of the time on my machine running Ubuntu.
• 0% of the time on Windows.
• (0% of the time on macOS?)

A workaround if you get this issue is to run Atom from the command-line or terminal with the --disable-gpu flag.
