Issue Description
In a Gnome Wayland session when I select some text in gedit (Gtk3) or gnome-text-editor (Gtk4) and then call IBus.Engine.get_surrounding_text() I get always the same cursor and anchor positon, i.e. it looks as if no text was selected:

The code which prints the above log messages looks like this:
def _command_show_selection_info(self) -> bool:
'''Show info about the currently selected text'''
if not self.client_capabilities & itb_util.Capabilite.SURROUNDING_TEXT:
LOGGER.info('Surrounding text not supported, cannot get selection')
return False
surrounding_text = self.get_surrounding_text()
if not surrounding_text:
LOGGER.debug('Surrounding text object is None. '
'Should never happen.')
return False
text = surrounding_text[0].get_text()
cursor_pos = surrounding_text[1]
anchor_pos = surrounding_text[2]
LOGGER.debug(
'surrounding_text = [%r, %s, %s]', text, cursor_pos, anchor_pos)
selection_start = min(cursor_pos, anchor_pos)
selection_end = max(cursor_pos, anchor_pos)
selection_text = text[selection_start:selection_end]
LOGGER.debug('selection_text = %r', selection_text)
if selection_text == '':
LOGGER.info('Nothing selected.')
return False
[... more stuff...]If I do the same test in a Gnome Xorg session, I get the correct selection in gedit and gnome-text-editor, it fails only in firefox in a Gnome Xorg session.
In the Gnome Xorg session, gedit uses the Gtk3 ibus input module and gnome-text-editor but uses the Gtk4 ibus input module. In the Gnome Wayland session, both gedit and gnome-text-editor use the Wayland input (ibus passes gnome-shell on focus in).
So think there is something wrong with getting surrounding text when using Wayland/gnome-shell input.
I am not sure whether this is an ibus or a mutter problem so I report it first here.
If it is not ibus but mutter or something else, I can move the issue there.
Steps to Reproduce
- Use ibus-typing-booster >= 2.27.54
- Define a keybinding for the command `show_selection_info` in the keybindings tab of the setup tool. For example `F2` works.
- in a terminal, follow the log file and grep for the `show_selection_info` function: `tail -F .local/share/ibus-typing-booster/debug.log | grep selection`
- Start gedit, type something, select text in gedit and hit `F2` (or whatever you defined as a keybinding)
- In the terminal one sees that the cursor positon an anchor position reported by `get_surrounding_text` are always identical, no matter whether there is a selection or not.
When doing the same test on any Xorg session (Gnome, XFCE, i3, ...) the cursor position and anchor position returned by `get_surrounding_text` correctly show the selection when using gedit or gnome-text-editor (but not when using firefox, different problem maybe ...)Can you reproduce your problem when you restart ibus-daemon? (yes / no)
Yes.
Do you see any errors when you run ibus-daemon with the verbose option?
No.
Can you reproduce your problem with a new user account instead of the
current your account? (yes / no)
Yes
