Issue reproduced with gedit on GNOME + Wayland.
Description of problem:
When typing Sinhala text with ibus, the characters shake and wobble, making
writing experience uncomfortable. Letters sometimes disappear for a moment and
reappear. Two cursor positions or wrong cursor positions seem to appear during
the process. The latter is somewhat similar to the issue described here
https://gitlab.gnome.org/GNOME/pango/-/issues/684
Version-Release number of selected component (if applicable):
How reproducible:
Reproducible throughout the system.
Environment : Fedora 37 beta, GNOME on Wayland.
Applications : Gedit, Firefox, LibreOffice.
Steps to Reproduce:
1. Enable Sinhala input with si-wijesekera
2. Type : isxy, NdIdfjka ,sjSfua oS wlqrq Tn fudn mksk whqrq ksrSlaIKh lrkak'
(සිංහල භාෂාවෙන් ලිවීමේ දී අකුරු ඔබ මොබ පනින අයුරු නිරීක්ෂණය කරන්න.)
3. Typing any meaningful chunk of text can actually demonstrate the issue.
Actual results:
See attachments
Expected results:
Smooth typing without shaking, wobbling and disappearing/reappearing of
characters. The issue is already there to a lesser extent on Fedora 36 too. So
I am unable to show you a video of the ideal expected result at the moment.
