Unreal Engine 5.5 on Linux (Pixel Streaming) – Rendering Issues (Red, Blue, Green Tint)

Development Rendering

Hi everyone,

I’m encountering a major rendering issue after deploying my Unreal Engine 5.5 project on Linux using Pixel Streaming 2. The project was developed on Windows with DirectX 12, but when running it on Linux (Vulkan), the colors are completely off.

Issue Description :
The scene is displayed with an intense yellow tint (see attached screenshot), but it sometimes shifts to blue or red randomly.
The lighting and materials seem broken, making the environment unusable.
It looks like either textures, post-processing, or the rendering pipeline are not behaving correctly under Vulkan.

  1. Has anyone experienced extreme color shifts like this on Linux (Vulkan)?
  2. Could this be related to Pixel Streaming 2 on Linux, or is it a general Vulkan issue?
  3. Any ideas on what settings I should adjust to get correct color rendering?

System Details:

  • Unreal Engine 5.5.4
  • Running on Linux (Vulkan) with Pixel Streaming 2
  • Originally developed on Windows (DirectX 12)
  • Using Lumen for lighting and high-resolution textures

Any help would be greatly appreciated! Thanks in advance.

Hi there,

The extreme color shifts you’re experiencing are more likely related to the rendering pipeline or Vulkan configuration rather than Pixel Streaming 2 itself. I recommend trying to repackage and recompile your project from scratch on Linux, ensuring that all shaders and assets are properly rebuilt for the Vulkan environment. This step can often resolve such rendering inconsistencies.

Additionally, for high-quality scenes, Windows remains the preferred OS, especially when using DirectX 12, as it typically offers better compatibility and performance with advanced rendering features like Lumen.

If you’re open to exploring alternatives for Pixel Streaming, consider Streampixel. They provide high-performance machines optimized for Unreal Engine and offer cost-effective solutions, which could be a great fit for your project. (We used their service)

Hope this helps! Let me know how it goes or if you need further guidance.
