MuseScore 4.1.1 download the last version for windows

When it is idle, it should use no CPU at all and should not drain one's battery: one should be able to have an unused opened musescore in some window without any bad consequence. I expect a program such as Musescore to use CPU only when it receives some UI event, do some computation or perform some playback. If I do the same thing, but with a simple staff instead of a symphonic orchestra, Musescore's CPU usage is at about 8%, which is smaller but still big, It tells me MS4 is using about 34% of my CPU, even though it does absolutely nothing. I wait about 10 seconds for Musescore to load all of its audio samples, minimize the window (to be sure it receives no mouse/keyboard event), and run 'top' (for monitoring cpu usage). To reproduce, I start MS4, select 'New score', choose 'symphonic orchestra'.

I observe that MS4 uses a lot of CPU for scores with many instruments, even when idle, even with a new empty score. My laptop is from 2019 and was high end then (Dell XPS13). On a linux laptop, with the appimage for musescore 4.0alpha2.
