Package: libwxgtk3.0-gtk3-0v5 Version: 3.0.4+dfsg-9 If something is drawn by wxWidgets and is horizontally scrollable if wxWidgets uses GTK3 it is likely to flicker on redraw.
Upstream bug report: https://trac.wxwidgets.org/ticket/18462. The problem is reproducible by the maintainer of wxWidgets. It doesn't happen in wxWidgets3.1, which (as it is a development version) isn't packaged with debian.
