There is a black flicker for a fraction of a second just after the splash screen is shown. The main page is image heavy, probably it is because of that. While debugging I can see that some symbols are being loaded? Is it due to that? Is there any way to mask it? Or how do I show the MainPage faster with out the flicker. Can I preload the MainPage while the splash screen is shown?

In other words, can a PWA splash screen just be a solid custom color?
In my PWA, the splash screen occurs so quickly, there's not enough time for a user to register what they're seeing. It could be perceived as an error/problem or just simply sloppy design.
For reference, the site is online, I'm using wireless (LTE) on my phone, and service worker cache disabled. I haven't yet tried it with the service worker cache enabled, but I assume the splash will disappear even faster!
For a PWA splash screen, I'd rather just have a custom solid color (which would match my website background).
Use an icon that is the same color as your splash screen background color. The icon will then not be visual different from the rest of the splash screen.
According to https://developers.google.com/web/tools/lighthouse/audits/custom-splash-screen, a splash screen must have:
A name property in the manifest
A background_color in the manifest
Icons set with one at least 512px by 512px
The Icon being PNG format
This does not leave the option to leave out any of the previous settings.
However, you can set the icon to be a solid color with the same color as the background. This should make it so that the user cannot see any icon.
As a dimming/darkening work around to the notorious white flash in between Chrome page loads, how could the small default loading notification (below) be exploited to cover the entire screen?
In other words, is it possible to create an entire wall of text in between page loads such that a high contrast extension could then darken the entire screen just as it darkens a small portion here?:
This is quite hacky, but for good reason. All other solutions no longer work for Chrome 40+:

No, it's not possible to change what that status bar shows, not without digging into Chromium's source (but then you could just change how about:blank looks).
The idea is indeed way too hacky.
I am facing strange issue in Splash screen of windows phone 8.1 store app.
Scale Image size (pixels)
1x - 480 x 800
1.4x - 672 x 1120
2.4x - 152 x 1920
Thses standard sizes I have given. Although Image does not look proper in 4.7 inch 720P devices.
Any help is appreciated.
I don't think theres much you can do to improve this (except like #neoproudek suggested using ExtendedSplashScreens)
But depending on your senario, you may only have to change the Splash Screen Background Color to a color that accommodates the Splash screen image color. Thus if you have a single color background splash screen image, such as the Windows Phone Music app with an Empty Splash Screen Background Color it will look like this:
But changing the Splash Screen Background Color to #107C0F like so:
Quick note: Splash Screen Background Color does not have an alpha component
The end result is a good looking Splash screen:
Hope this helps!
You can (only) do it with just images (through appxmanifest) if you prepare the splash screen so, that the top and bottom parts are in uniform colored fill, which you can seamlessly extend to the top and bottom of the screen by setting the Splash Screen Background color in Package.appxmanifest.
I meet a problem on mgwt development and wanna ask for help here. I am developing an application using MGWT and phonegap. And there will be some animation which will interact with user like swiping a panel with an background image. I implemented it by using Css translation. It works fine in browser(both chrome and safari) and in iphone. I use MGWT to create the home page with a scrollPanel in the middle, after clicking the items in the scrollPanel, a touchPanel will swipe to the center to cover the homePage. This swiping animation is done by Css translate3d(x,y,z).
However, when I deploy the application to iPad 4, the background color(using css) start flickering during the panel translation. the scrollPanel in the home screen keep flickering for around one seconde( I guess it is rendering), part of the items disappear and the part of the white background ground is show. The problem also appear in the touchPanel's content. I tried some suggested solution like hardware acceleration using translate3d(0,0,0) but seems it doesn't work.
Do any body know why? Please help, thank you.
Does anyone know why PrintJob produces such a low quality blurry results and how to fix this?
This is because HtmlLoader renders itself as a bitmap with screen resolution (around 72 dpi). I got decent result printing it following way:
Scale up html body by setting style zoom:400% on it (via JavaScript function injected into page)
Scale it down to normal with scale=0.25 (on HtmlLoader object)
(got idea from here)
This raises resolution of HtmlLoader bitmap in factor of 4. Pictures will stay blurry (if they have screen resolution), but text will be OK.
