Blank windows with chromium-args (in-process-gpu)

NWJS Version : 0.39.3 32/64 bit (Windows normal/sdk) and nwjs-v0.40.0-beta1-win-x64 (normal/sdk)

Operating System : Windows 10 32/64 bit

Expected behavior

The application (nw.exe) should start normally like my older version 0.30.5 (I need an NW update because I need add vibration for the gamepad for some players 😄).

Actual behavior

Using “chromium-args”: “–in-process-gpu”, in package.json will cause windows (including DevTools - chrome-error://chromewebdata/) to be “blank/black”.

It works when I remove “–in-process-gpu”, but I have low fps on some devices (low-end).

How to reproduce

This is my package.json. You can try load credits.html, for me windows is black/blank like on the screenshot. I can drag credits.html (or game files) to nwjs window (nw.exe) and then it works…

{
	"main": "credits.html",
	"chromium-args": "--in-process-gpu --disable-transparency",
	"version": "1.37.51",
	"window": {
		"toolbar": false,
		"fullscreen": true,
		"width": 900,
		"height": 510,
		"resizable": true
	},
	"webkit": {
		"plugin": false,
		"page-cache": false
	}
}

PS. I will check later Mac OS / Linux.

I had the same problem on win10 (didn’t check other systems). My devtools window was blank, my main window was simply transparent with shadow around it. It was still usable, everything seemed to work fine by navigating through it blindly but it just didn’t render any of the windows. Downgraded to 33.3 and it works perfectly now.

Maybe it’s gpu/driver related? Mine is AMD R9 290x with drivers: 18.50.21.01-190212a-339148E-RadeonSoftwareAdrenalin2019
