fail to run project on ubuntu,it shows "Display: Encountered a new graphics PSO" at last.

after building the package ,i run it in linux
also singallingWebServer is running
the cmd is like: /somepath/myproject.sh -PixelStreamingURL=ws://127.0.0.1 -RenderOffscreen

it show “Display: Encountered a new graphics PSO” ,and the log do not continue any more

here is my environment:
ue editor’s version is 5.2
linux: ubuntu 20 ,and i entered the system in command-line mode

i cannot attach the log file (new user) ,so i just attach the last content here

Hi there!

The “LogRHI: Display: Encountered a new graphics PSO:” logs are standard and can be safely ignored.

Can you confirm if the application is running properly? You should be able to connect to it via the stream through your browser.

when i run this program and the SignallingWebServer show only two pieces of messages

unknown ← {“type”:“identify”}
LEGACY → {“type”:“endpointId”,“id”:“DefaultStreamer”}‘’

when i open the website ,the chrome’ console show;

Level: Error
Msg: Message type of identify does not have a message handler registered on the frontend

But i see the same example which is running on the window copy. the win SignallingWebServer show more websocket messages than this.

and also ,the windows program show more logs than the linux one,just like these:
