I broke the Unity splashscreen. Sorry?

Hello everyone!
I just tried to do some optimizations on an app that I'm working on and after doing so, the Unity splashscreen is gone, sort of. When I build for iOS, there is still a blueish dark grey background showing up. The color looks like this is the background of the Unity 5's splashscreen. But the Unity icon is missing. After a few seconds, the plain color will go away and my splashscreen will appear.
Has anybody had a similar problem at some point?
I guess I'm not allowed to release builds like that, right? I'm actually trying to finish that app as soon as possible and get it approved by Apple. I don't have Unity iOS Pro, though.
Also, I don't really know if this is an iOS-specific problem or not, so I posted it here.

Oh, and just to make sure: I even checked
Player settings -> Splash image -> Show Unity Splash Screen
and it didn't work either. This was turned off before by default and Unity always included it. Well, until now.

EDIT:
Some more information here about the optimizations I made: Nothing fancy, I just noticed Unity is actually loading assets while displaying its splash screen. So I moved my splashscreen into the titlescreen so that it doesn't switch scenes in between, which saves loading time.

EDIT2:
Here's a screenshot, too:


Many thanks in advance for any help!

Sure thing. Will do ASAP. Thanks for the reply.

@karl.jones Alright, I just tried to size down the project to the relevant part, but then it will work. I will send in when I can reproduce this.

 

@karl.jones I'm uploading the report right now. While reducing the project to the affected parts of the game, I found out about some things that might speed up resolving this. More details are included in the report.

 

Hi @Shushustorm @karl.jones , did you manage to fix it? The same thing happened to me and I've tried everything to fix with no results, I'm on unity 5.2.1p1.

 

Thanks for the answer @karl.jones , I've been checking the patch releases but didn't find the fix on the release notes so we haven't make the update and stick with 5.2.1p1 for now, but I'll download it later today to see if that patch fixes the bug, thank you!

 

I'd be curious if that does fix it... i'm seeing the same behavior, and sometimes.. the logo will 'flash' for just may .25 seconds (if that even) before the game shows its' first frame.

 

I actually uploaded a bug report on Sep 8, 2015:

I don't know about the bug number, though.
Unfortunately, I cannot confirm that the problem has been solved in a newer version, because I used a workaround to get rid of the problem. But it should be fixed. When I have the time, I will take a look into this and try to undo the workaround and test on 5.2.2.. If I do so, I will keep you informed.

Also:

@tswalk
The workaround is pretty simple (maybe it works for you, too?): Put all of your code included in Start() on hold for a frame:

Code (CSharp):

1. void Start () {StartCoroutine(Start_());}
2. IEnumerator Start_ () {
3. yield return null;
4. // your start code here
5. }

or maybe even:

Code (CSharp):

1. IEnumerator Start () {
2. yield return null;
3. // your start code here
4. }

 

I just tried to undo the workaround, but the problem wouldn't show up anymore.
So I thought the update fixed it, but after running the project in 5.0, the problem wouldn't show up either.
I guess it's either a specific problem of a certain patch release that I used or the problem has been solved permanently after making it compatible to open in 5.2.x.

@povilas
Alright, this is quite irritating. I am running into this again.
I installed Unity 5.4B10. Now, when I run a 5.4B10 build, there will be a different Unity splash screen (a white one! Is it different because it's beta?), but it will only show up for a very short time just before the game starts. I guess it's not intended like that.
Then I thought, I will be fine, because it's just a 5.4 beta bug and I still keep a 5.2.2 copy of my project and Unity 5.2.2. But now, after building in 5.2.2, the splash screen of 5.2.2 builds will be completely gone just like the first time this issue appeared.
Any ideas how to fix this?

EDIT:
New screenshot, because it looks different.
There is a small black border on the bottom:

 

I tried deleting the app, reboot the device and use a differnt bundle ID, but unfortunately the issue remains the same.

EDIT:
I also cleared the following folders, which didn't solve the problem:
HD/User/Me/Library/Developer/Xcode/DerivedData
HD/User/Me/Library/Developer/Xcode/iOS DeviceSupport
HD/private/var/[...]/com.apple.DeveloperTools

 

Case number for this issue: 725746

Also, maybe this is useful: I am getting the following warning when building:
