I have not seen this happen or had it reported before. Are you using Supersonic via a native Wayland build (which is still experimental) or through xwayland? Also, which view is slow to scroll? (tracklists, grid view, or both)?

On the grid view it is really slow and laggy, on the track view its fast but also laggy. Kinda hard to describe

I'm using the bin here from the AUR https://aur.archlinux.org/packages/supersonic-desktop-bin

Maybe a screen capture may be helpful. I can't reproduce this on any of my systems so a video might help to get a sense of what could be going on.

After I start scrolling I take my mouse off the scroll bar and it keeps going on its own. You can't see my cursor in the video but it's not on the scroll thing

Oh, do you by chance have a mouse that reports an insanely fast rate like 1000 Hz? I remember someone else having a similar issue with a different app built with the same toolkit (Fyne). If so, unfortuantely there might be no fix right now other than to use the keyboard arrows to scroll instead, or changing your mouse speed. Eventually, the toolkit will have to do some internal handling to not respond to every scroll request if they come in too fast. I will try to see if it's been reported there as a bug and get it prioritized.

no i dont think my mouse has an insanely fast rate. is there a way to check reliably? i have 800 dpi also

Wanted to tack on that I'm similarly experiencing jumpy/laggy scrolling on an M1 Pro Macbook Pro when scrolling with the trackpad. MacOS version is Sonoma

For those seeing this issue, does it happen on all scrollable views, or only on the tracklist or only in grid views? I cannot reproduce the issue at all with grid views, and with list views it is just a tiny bit unsmooth on my M1 Macbook with the trackpad

It's unsmooth scrolling in all views, the more prominent jumpy/stuttering scrolling is on the grid views. The artists view in this screen really shows it, very jumpy, like the content is constantly changing.

Oh, OK I think the "jumpy" scrolling is a separate issue from the "laggy" scrolling. I had honestly just gotten used to it, but it's from the UI toolkit's scroll accelerate logic - when scrolling faster than a certain fixed speed, it multiplies the scroll speed by an acceleration factor to accelerate it further. This maybe could either be disabled for Mac, if MacOS handles scroll acceleration itself anyway, or else improved to a more smooth function with no discontinuity.

I created an issue in the UI library for this

Jumpy scrolling on Mac will be resolved when fyne-io/fyne#5068 is merged in
