Created attachment 463394 [details, diff] The patch Newer versions of gtk+ have changed the behavior of the gtkfilechooserwidget, where typing the first few letters of a filename do not jump to the first file with that prefix, but rather performs a recursive directory search. This makes using the filechooser nearly impossible when dealing with large directory trees in systems with slow hard drives. It is also a general irritation during use for some users. There is a well-maintained patch on the arch linux AUR that restores previous functionality and it is trivial to apply this to gtk+ on gentoo via /etc/portage/patches. However it would be very useful if we could provide this patch optionally via a USE flag on the gtk+ ebuild. Here is the link to the AUR version of the patch: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=gtk3-typeahead I am also attaching my patch. It works with gtk+ upto v3.20.9 (I haven't tested higher)
