Mixxx faces big challenges moving to Qt6. Maybe someone skilled with graphics programming and Qt can give us some advice?

I suspect we're hugely overcomplicating things just to get smoothly scrolling waveform animations with our current implementation, but I don't know much about graphics programming.

Please boost (the first toot in the thread).

The general problem is: How do we time the rendering of a smooth animation representing a one dimensional continuously changing variable (position within the audio track) which can change in either direction?

Maybe a PID controller would be the tool for this job?

Maybe post again with some hashtags like #Qt #graphics #GUI ? People who are passionate or knowledgeable about things often monitor hashtags related to them.
