Empty quick app consumes cpu on doing nothing (multithreaded Qt build)

MS_36 · wrote on 7 Nov 2019, 10:24

Hello!

I have Qt 5.14 Beta 2 built with emscripten 1.39.0 with multithreading support.
Building and running the "Qt Quick Application - Empty"-template from QtCreator in the browser(FF + chrome) shows that the corresponding process takes continuously more than one thread of my cpu to run it.
I am not sure if this also would be the case if the app was built with multithreading disabled.

Is this normal at this stage or should I consider opening a bug?

Best regards
Markus

It's probably normal, but you could open a bug about it anyway.

Okay, thanks!
I would prefer it to use less CPU in that case so I will open a bug after I tried it without multithreading.

Edit: Single threaded its fine (QTBUG-79953)
