The rows in a GtkTreeView with separators glitch as you move your mouse over it in Lubuntu 18.04 fresh install.
Spotted in Exaile music player (originally reported as https://github.com/exaile/exaile/issues/527).
The issue disappears after switching to a different widget style, e.g. Clearlooks. The issue didn't exist in Lubuntu 16.04 default theme.
A similar bug fixed in Ubuntu Ambiance theme https://bugs.launchpad.net/ubuntu-themes/+bug/1701512
