macos 10.13 issues

[starpit]

two issues with macos 10.13:

1. screen shows blank for a short duration, then flashes over to the actual content
2. the terminal shows this message:

IBM Cloud Functions Shell[61208:2254181] *** WARNING: Textured window <AtomNSWindow: 0x7fefb4e978b0> is getting an implicitly transparent titlebar. This will break when linking against newer SDKs. Use NSWindow's -titlebarAppearsTransparent=YES instead.

this electron issue may cover it: electron/electron#10559
or this? electron/electron#11150

Same issue here with a simple code.

const electron = require('electron');

const { app } = electron;

app.on('ready', () => {
  console.log('App is now ready');
});

my console

App is now ready

Update. If i add app.disableHardwareAcceleration() to the code, the app works fine.

const electron = require('electron');

const { app } = electron;
app.disableHardwareAcceleration();

app.on('ready', () => {
  console.log('App is now ready');
})

console

App is now ready

thanks for digging into this @hmontes !

disableHardwareAcceleration doesn't seem to remove this message:

*** WARNING: Textured window <AtomNSWindow: 0x7fe84d46d900> is getting an implicitly transparent titlebar. This will break when linking against newer SDKs. Use NSWindow's -titlebarAppearsTransparent=YES instead.

@starpit I updated my code. You need to put that line before the app is ready.

(My mistake. Sorry)

Official doc: https://github.com/electron/electron/blob/master/docs/api/app.md#appdisablehardwareacceleration

I think the problem is related with the Macbook models. Some models have Nvidia gpu's, others (like my laptop) has an intel gpu.
