pixel streaming jitter and blur

Hey

I have successfully deployed pixel streaming application(version 4.27) and made it work.UE4 Client is smooth,no jitter. FPS:50.
I’m using the following setup:one signalling webserver, one ue4 client,chrome browser, all within LAN.
My computer Hardware:I7-12700K, 32G RAM, GPU RTX3080TI,Wi-Fi connection

I have two questions:
1.Visible jitter in the browser when quickly rotating the camera or playing the timeline.
2.The image is blurry in the browser.

Any idea or hints,I expect a response and an answer from all of you guys.

Best Regard!
