Drag the left border of an electron app and you’ll see the right border flicker.
Why does it do that?
It happens on the most basic apps - you can create an app that has nothing in it and it’d still flicker on resize. It’s also interesting that the flicker is much heavier when you drag the left border of the window than if you drag the right one.
This might seem like a small issue, but Electron apps would feel much more native with this issue gone.
I’m on Mac OS, but I believe that the issue can be reproduced on all OSs.
