It seems xim support in GTK3 is known to be buggy and GTK upstream say: the recommended fix is not to use xim https://gitlab.gnome.org/GNOME/gtk/-/issues/2560#note_757143 Support for xim has been removed completely in the development branch which is leading to GTK4: support for the xim input method has been removed in favor of IBus https://blog.gtk.org/2020/02/13/gtk-3-98/ Cheers, Olly

The upstream ticket has been in state "infoneeded_new" for more than 3 weeks requesting you explain how to reproduce this in the "scroll" sample - so far without response. Tagging this "unreproducible" which roughly matches the upstream status, and because neither Scott nor myself seem to be able to reproduce this based on the information you've so far provided.

> Do either of the suggestions pcor makes on the upstream ticket help? Unfortunately not. But thanks for the heads up: A spambot that has run wild has flooded my inbox with one mail every 90 seconds and I therefore didn't see the answer to my bug report there. Kind regards, Gunter.

Bug#934386: wxScrolled flickers when the horizontal scrollbar is active and GTK3 is used
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.
