Before, the gradient transparent black overlay made text hard to read in some cases. Torrents without a poster image showed up in blue-gray and didn't look good.
This gets rid of the light gray to dark gray background color change on
the main window at startup. Makes the window show slightly later, but
it's gray for less time. Doesn't affect overall startup time. Feels
less jank IMO.
From the Electron docs:
> While loading the page, the 'ready-to-show' event will be emitted
when renderer process has done drawing for the first time, showing
window after this event will have no visual flash.
Every require() that we do before the users sees UI reduces startup
time.
I used the following code (added to index.js) to log every require()
call in the main process:
```js
var Module = require('module')
var required = {}
Module.prototype.require = function (orig) {
return function (id) {
if (!required[id]) {
required[id] = true
console.log(`${id} (from ${this.filename})`)
}
return orig.apply(this, arguments)
}
}(Module.prototype.require)
```
From this I was able to learn that lots of modules were being required
that aren't actually used until later.
I also sent this related PR to eliminate another few require()s:
https://github.com/LinusU/node-application-config/pull/4
This increases startup time by 50ms.
We'll probably realize much bigger gains by following this same
procedure for the renderer process.
- Make State.save() always throttle calls -- since that's the common
case.
- Immediate saves are now the exception, with State.saveImmediate().
- The function is called State.save(), so the dispatch event should be
'stateSave'.
On my modern Macbook 12" I've run into "Saving state took too long.
Quitting.". We have users with spinning disk drives, so let's be a bit
more generous.
