App no longer renders anything after playing audio

[labo-China]

I`m currently trying to run my music player app on textual-serve.
App launches without problem. And everything goes perfectly until I played a audio via pyaudio locally.
When I play any audio, the frames just goes frozen. I cannot see anything newly updated on the screen.
I believe that the network connection is OK because buttons works well (if I click at the position where they are lastly painted) and BINDINGS also works. I open the Developer Tools on my browser and it can be observed that the WebSocket connection is still sending resize events correctly.
I have no idea what to investigate, as I didnt have any experience on this project. I will be happy if any help is offered.

I am running all of this on Textual 0.79.1, tetxual-serve v1.1.1, ungoogled-chromium 127.0.6533.72（Official Build, ungoogled-chromium）.
