@rogerwang The problem is still there and I just noticed that I failed to include another detail so that this issue can be reproduced. I have updated the main issue with the missing detail. The window also needs to be set to always_on_top: true. Without that, the problem does not exist.

So to summarize: Frameless + transparent + always on top causes this issue, even with the latest RC1 you just shared. Removing either one of those three options makes the window behave correctly when maximized.

@Yonezpt can you sent us your sample app ?

jtg-gg on 13 Oct 2017

@jtg-gg Certainly, sorry for the delay. This sample app makes use of the package.nw folder method. The contents of that folder are the two files below:

package.json

json { "author": "test", "description": "test", "main": "index.html", "name": "test", "version": "1.0.0", "window": { "id": "test", "always_on_top": true, "frame": false, "transparent": true } }

index.html
