Let me summarize: - A pop-up that appears always when pressing the controllers Load button would disturb the standard workflow. We shouldn't show this just to suport this special workflow....

You could try if the experimental VSync mode PLL described here https://github.com/mixxxdj/mixxx/wiki/Changing-the-VSync-Mode-for-Scrolling-Waveforms improves this.

I see this on Windows 11 too

You could try the build from PR #12904. The Link _Ubuntu 22.04 DEB_ at the bottom of https://github.com/mixxxdj/mixxx/actions/runs/8123807324?pr=12904 It prevents some kind of waveform jerking, but I guess this here...

I guess one reason are the ToolTips. @tbazant Could you try to disable the tooltips in the preferences. Does this improve the waveforms?
