Chromium CPU utilisation 100%+ - simonb - 10-01-2024
I’ve got a problem with chromium CPU utilisation. Chromium runs at well over 100% CPU utilisation when using the internal screen.
PRi4b 4Gb ram, 7 inch RPi Touch screen. Latest cut of Moode.
Running the top command with just album art on the screen:

@simonb
As a matter of forum etiquette, you should be posting code and/or terminal output into a code box (see the scroll-with-plus-sign icon above the edit window. Also, point releases of moOde roll out quite frequently. Terms like "latest cut" are nebulous---today we're at r9.1.2.
As for the CPU usage, I'm away from a player with official RPi 7" touchscreen attached. I seem to recall, though, that the bouncing icon---called "Equalizer(Animator)" in the Now-playing icon menu on the Preferences screen---is quite CPU-intensive with the local display enabled. If you have it on, try selecting the static "Waveform" icon instead.
Just my 2-cents worth.

Kent

I tried the code box as you can see it doesn't format correctly. Latest cut is up to date at the time of posting. I'll try removing the animation and check. Thanks for your reply.

I can confirm it's made a difference:
