[Pkg-mpd-maintainers] Bug#902430: sonata is very slow when mouse scrolling within a big library

[cacatoes at tuxfamily.org]

Package: sonata
Version: 1.7~b1-2

Hello again,

Since the port to GTK3 / version 1.7, I have trouble navigating the
music library with mouse scroll.

Library view mode is filesystem directories, and I am not even sure
"album" view does work because of it being too big (thousands albums).

The interesting part is, I have no trouble when using keys to spell the
first letters, so I can jump from one part of the list to another.

However as far as I scroll a little with mouse, the GUI becomes
unresponsive.

Also, it seems I can scroll smoothly with mouse the "current" playlist
tab, probably because I don't have it too big.  And I can also scroll
within sections of the music libraries which aren't too big.

Thanks for keeping alive the project,
