Description	Flags
Video showing the problem when using ibus-typing-booster in Gnome Wayland	none
Video showing the problem when using “Vietnamese (telex (m17n))” in Gnome Wayland	none

Description Mike FABIAN 2021-03-12 15:26:09 UTC

I installed Fedora-Workstation-Live-x86_64-34-20210308.n.0.iso into qemu.

Add the ibus-typing-booster input method in the Gnome control center and
also add the “Vietnamese (telex (m17n))” input method from ibus-m17n.

Both input methods use 

   update_preedit_text_with_mode(..., .., ..., IBus.PreeditFocusMode.COMMIT)

and this problem can be reproduced with either of them.

Open a gedit and a gnome-terminal.

Select ibus-typing-booster in the Gnome panel and type “test”.
The word “test” is underlined, indicating that it is in preedit and not yet committed to gedit.

Now click on gnome-terminal to change the focus to gnome-terminal.

The string “test” vanishes from gedit. It should *not* vanish, it should
be committed i.e. the underline under “test” should vanish and the string
“test” should be in gedit.

Same problem with the Vietnamese (telex (m17n)) input method.

Select it in the Gnome panel.

Type “a” into gedit.  The “a” is underlined because it is in preedit.
Click on gnome-terminal to change the focus to gnome-terminal.
The “a” vanishes. Here as well the “a” should be commited to gedit, i.e.
the underline should disappear and the “a” should remain in gedit.

This works fine in Gnome Xorg.

Sorry, this is not a regression but a known issue.
ibus_update_preedit_text_with_mode() has not been implemented in GNOME Wayland yet.
pwu has the patch of the API and I have another patch over his one.
