Hi,
I believe this issue is related to the following, caused by images being repeatedly loaded from disk:

Can you confirm that by "jittery", you mean you are getting a low framerate? Does your framerate improve if you significantly decrease the size of the window (thereby reducing the number of images that have to load)?
That seems likely (that it's a caching issue).
By jittery I meant that the album thumbnails disappear and reappear (blinking) while scrolling so introducing a sort of jumpiness into the scroll.
I should mention that the media library itself is on an external NAS (connected via USB 3 at the moment, haven't hooked up LAN yet), so that might also exacerbate any read-time/latency.
At my fullscreen resolution, I see an 8 x 5 grid of albums, when I reduce the size of the window so it shows only 3 images across there is a reduction in jitter.
Edit: Just a note. If I use the scroll bar to scroll instead of mousewheel (or trackpoint and middle click) there is no jitter.
