Title:
Spurious "key_press_event" when focus on entry widget using
LANG=th_TH.UTF-8
Status in GTK+:
New
Status in gtk+3.0 package in Ubuntu:
New
Bug description:
GTK+3 will emit spurious "key_press_event" if the focus is currently
on "GtkEntry" and the locale is set to th_TH.UTF-8. This issue seems
to disappear if the locale is set to something else (tested with
C.UTF-8 and en_US.UTF-8), and the presence of iBus and gnome-shell
affects this.
Step to reproduce:
1. Boot into Xubuntu. Install package "language-pack-th" (for locale) and
"libgtk-3-dev" for compiling demo program.
2. Download & compile the demo program "gtk3-entry-keyboard-event" attached
in this bug. (The program is licensed under MIT.)
3. Run the program with LANG=th_TH.UTF-8. The window will contain an input
box on top and a button on the bottom.
4. Click in the input box, then press a key on the keyboard. The program will
print one line for each "key_press_event" delivered to the window, with keyval
and hardware_keycode.
Expected result: only a single line is printed. For example for "a":
"window: 0x0061 0x0026"
Actual result:
- With LANG=th_TH.UTF-8, two lines are printed. The first line is the above
line, while the second line has both values as zero: "window: 000000 000000"
- If, instead, the locale is LANG=C.UTF-8, the program will print only one
line as expected.
- If iBus is installed and enabled, then 2 lines are printed with both
lines containing the same code, no matter which locale it runs under.
- If this same program is run in Gnome-based Ubuntu session, then only one
line is printed no matter which locale it runs under.
This program is tested on Fedora and Manjaro with the correct result.
Thus, this issue is Ubuntu-specific.
I've tested it on Ubuntu 19.10 with pretty much the same result,
except the iBus case is now working correctly.
