Colour problem Xbox One when game set to Game Mode

Hello,

I have a game which I've got set as a UWP build and I am deploying it to the Xbox One.
When I run a game game on the Xbox One S it is set as an App by default. When it is set as an app the colours are normal. However, when I set it to Game, then the colours change, specifically in gradients.

I have attached a few screenshots to see this.
Compare the engine glow at the back of the ships in these two screenshots.
On the 3rd screenshot you can see the effect when looking at the colours of the nebulas on the skybox

Does anybody know what is causing this?

Thanks in advance.

 

I don't know. How can I find out?

Thanks for your reply.

 

Thanks.
That property tells me I'm using Direct3D11.
So I guess that even if the Xbox is running in Game mode, it will still run in DX11.

 

The background is a Skybox, don't know if there is anything unusual about it or not. The shader is Skybox/6 sided
However, looking at the particle used for the ship, it does say it's using the default-particle, and the Shader is Legacy Shaders/Particles/Alpha Blended Premultiply.

I've never used FrameDebugger before, do you have a link to a tutorial that could get me started and I'll have a look through it?
Thanks again for your help.

P.S. I've swapped the legacy shaders on the particle systems for URP shaders. Building now, let's see if it helps.

 

Ah yes, thanks.

Changing the shader on the particle system has helped a bit, but not completed.
I'll take a look at the link.

Thanks again.

 

It looks like both DX11 and experimental DX12 are in the player settings.
Maybe in Game mode the Xbox selects DX12 and that's causing the graphics problems?
I'll try removing it and seeing if it helps.

 

Removing DX12 from the player settings has fixed it. Graphics all look fine in Game mode now.

Thanks for your help.

 

I'm sorry I'm unable to replicate the bug now.

I re-added the DX12 (Experimental) option, made a new UWP build, ran it on the PC and it's fine. I created an appx package to run on the Xbox in Game mode, and that was fine too. I guess removing and re-adding DX12 has somehow fixed it.

Curious though, when I run the game in App mode on the Xbox, the 3D models disappear. I won't be running in App mode though so it doesn't concern me.

I do still have a graphical problem in DX12 which doesn't appear on DX11, but it looks different to this one, so I'll enter a new post for it tomorrow. But this one seems to be fixed by removing and re-adding DX12.

Thanks again for your help.
