or by applying its patch. Then, you can enable IME with [text-input-v1] by
running Chromium with `--enable-features=UseOzonePlatform --ozone-platform=wayland --enable-wayland-ime`.

# 12. GTK {#gtk}

In some recent GTK (>=4.16) applications the File Chooser defaults to using
xdg-portal technology which may not work depending on your system setup. There
are at least two ways to fallback to a 'normal' File Chooser:

1. Set the environment variable `GDK_DEBUG=no-portals` (in for example
`$HOME/.config/labwc/environment`)
2. Create a portal configuration file in the current user home based on
[labwc-portals.conf] and add the line `org.freedesktop.impl.portal.FileChooser=none`
to it. The location of this file should typically be
`$HOME/.config/xdg-desktop-portal/` but please see [portal-user-home] for
further details.
