Black screen after Unity Logo with ASUS EP121 X86 tablet on Windows 8

Syphius · August 2, 2013, 9:19pm

Hello,

I’m trying to port my game on Windows Store Apps.

The game already works with Windows Phone 8, Android and iOS.

When I start the game on my desktop PC on Windows 8 Pro everything works.

But When I deploy the game on my ASUS EP121 X86 tablet on Windows 8 Entreprise, just after the Unity logo, a black screen is displayed and nothing else appears.

This tablet have a Intel HD Graphic card.

I have no special logs on Visual Studio Debug outputs.

Is it a known bug? Could someone help me?

Best Regards,

Guillaume ORTEGA.

Hello,

I just tried the same test with a Unity Empty project with an empty scene (or with a red cube).
It’s exactly the same problem! a black screen after the Unity Logo.

Best Regards,

Guillaume ORTEGA.

I’ve noticed this as well… and it happens after the mainpage.xaml is loaded and rendered just prior to the D3D surface is created on the swapchainpanel… a black screen is displayed just briefly.

Hello,

For me it’s not briefly, the game block on this black screen.

I’ve also noticed that on other devices its briefly, but not on the ASUS EP121.

Best Regards.

This bug has been fixed in Unity, so wait for new release.
There is no such black screen if you use Unity PRO, only in Basic (which will be fixed in new release, as I said).

Hi,

Aurimas, i have the same problem in Windows Phone 8… Do you know if this bug is also present in WinPhone? Do you know when would be the new release published? Is there a temporal workaround to avoid this bug?

Thanks!

I found it occurred when I edited the splash screen image to rotate it to horizontal, upon rebuilding and leaving the image alone it went away.

Hi,

As far as I know, this problem was specific to Win Store Apps, the black screen is shown for a few seconds there. For how long is the black screen showing for you?

Hi,

I’m trying to migrate an actually working and published Android game with Unity free version (4.2.0f4) The black screen appears after the Unity splash logo and does not disappear, making impossible to continue…

I’ve changed some classes that didn’t work in WinPhone, but the app seems to run fine in the Unity IDE… (i’ve not try to deploy a simple project). Any ideas?

Thank you very much.

Did you check unity log on the phone after black screen happening?

caldofran · August 8, 2013, 12:24pm

I’ve no idea of how to do that… (as far as i know the profiler is not available in Unity free and have no idea of how to check any logs in WinPhone) if you mean if Visual Studio throws me a kind of a log, trace or exception… the answer is no…

The log is on the phone itself. To extract it you can use this software:

The log should be in isolated storage under your app.

This is the log… (those transform don’t exist in my project, maybe in the past when i started the app) I’m not sure that those logs are relevant…
