FFT bars wriggling around too quickly even to a sinewave #10

Hi,

I tried out the projekt and I recognized, that the FFT Bars in every viewtype are wriggling around (in level) very quickly, even if i have a constant sinus tone as input signal. Does anyone recognized this issue and knows the reason? I also tried out different fft sizes...

Thanks, Rob

Hi, you might want to limit the fps. Back to the day I made this, almost every phone is 60hz. Nowadays there are 90hz, or even 120hz, which is too much I think.
