profileGPU not working on Linux
Unreal Engine Version:
UE 5.5.4 (also tested on 5.4, same issue occurs)
Issue Description:
The profileGPU command in Unreal Engine on Linux does not display any valid data.
The GPU Visualizer opens, but all metrics (rendering times) are 0.0 ms.
The scene log also shows all GPU stats as 0.0 ms.
The issue occurs in both Unreal Engine 5.5.4 and 5.4.
On Windows, the same scene correctly displays GPU profiling data.
Steps to Reproduce:
Launch Unreal Engine 5.5.4 on Arch Linux (Vulkan).
Open any scene with active rendering.
Enter profileGPU in the console.
The GPU Visualizer opens, but all values remain 0.0 ms.
Expected Result:
GPU profiling should display correct execution times for rendering tasks.
Actual Result:
All values in the GPU Visualizer are 0.0 ms.
The log confirms that GPU stats are not updating.
