Bug 2008359

+++ This bug was initially created as a clone of Bug #1994700 +++

Fedora-Workstation-Live-x86_64-35-20210814.n.0.iso
ibus-1.5.24-13.fc35.x86_64
gnome-shell-40.3-2.fc35.x86_64

Using Gnome Xorg.

When typing somewhere, the candidate lists opens far below the cursor position.

When typing near the bottom of the screen, the candidate list is cut off at the bottom

When typing very close to the bottom of the screen, the candidate list even becomes invisible.

Tested with ibus-anthy and ibus-typing-booster.

Ibus-anthy candidate list cut off at the bottom.

I cannot reproduce your problem with the same gnome-shell and ibus versions in GNOME Xorg in Fedora 35.

Did you change a scaling or something from your screenshot?

--- Additional comment from Mike FABIAN on 2021-08-24 13:46:48 UTC ---

No, I didn’t scale anything. The screenshots and the videos show the whole screen 1024x768 pixels.

Still happens today on Fedora-Workstation-Live-x86_64-35-20210814.n.0.iso after “dnf update” and reboot.

--- Additional comment from Mike FABIAN on 2021-08-27 15:34:39 UTC ---

Now I have 

Fedora-Workstation-Live-x86_64-35-20210825.n.0.iso
ibus-1.5.25-1.fc35.x86_64
gnome-shell-41~beta-1.fc35.x86_64

and the problem is still 100% reproducible.

And now it doesn’t even work correctly on Wayland anymore!

On Xorg, the candidate list is far below the cursor position.

On Wayland, the candidte list is far to the right of the cursor position, *if* the cursor position is not at the very left of the screen.

See video.

The problem is still  unchanged after an installation of
Fedora-Workstation-Live-x86_64-35-20210829.n.0.iso
and then using “sudo dnf update” to install all current updates.

[mfabian@fedora ~]$ rpm -q ibus
ibus-1.5.25-1.fc35.x86_64
[mfabian@fedora ~]$ rpm  -q gnome-shell
gnome-shell-41~beta-1.fc35.x86_64
[mfabian@fedora ~]$ rpm -q mutter
mutter-41~beta-1.fc35.x86_64
[mfabian@fedora ~]$

Thank you for the report.
Seems Fedora 35 GDB does not work for me and when `gdb --pid $PID` is called for gedit, gedit unload im-ibus.so with GDB and I could not reproduce this issue.

Now I fixed a regression of IBus GTK3 module.

But seems the X coordinate is still not good in GNOME 41 Xorg. I will compare F34 and F35 GNOME.

I confirmed gnome-shell upstream already has the fix.
