I tried running some of the demos and I'm having some issues.

For example, with the tui demo:

$ go run main.go
Overriding existing handler for signal 10. Set JSC_SIGNAL_FOR_GC if you want WebKit to use a different signal
2023/01/25 13:22:20 Callback from JavaScript!! {"hello":42}

The following window appears:

I clicked cancel, and got nothing. So I hit Quit and got a black screen with a white cursor.

As other example (to demonstrate the feedback slowness), I ran the todo application.

A window pops up, but getting anything to render takes several seconds. I press "H", and then 3 seconds later the letter "H" appears on the screen.

Is this related to the RPC protocol?

Thanks in advance.
