Linux WebView high CPU usage #511

Open Hejsil opened 1 week ago

Hejsil commented 1 week ago

When running webui with WebView as the browser the program ends in the following busy loop:

This causes high CPU usage. Is there a reason why blocking = false is passed to gtk_main_iteration_do?

the program ends

You mean unwanted exit, like a crash? Or a normal exit?

I guess if blocking = true the websocket server will be blocked or something... you can easily test it to be sure. just change the line, and run make.

Aaah no. I guess that is bad phrasing. The program will spin on this loop (100% CPU usage) after opening a window. So the program "ends up" here once the window has been opened.

Aah ok. Just tested a little further. It does not seem this is the loop that causes 100% CPU usage. I just assumed (my bad)
