I mean ImmDisableIME.patch should be used as a workaround.
It's hard to get why SEGV happens because my build environment is brew scratch-build but not local.
Program received signal SIGSEGV, Segmentation fault.

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
When change Ja MS-IME to US with Alt+Shift or MS-IME to JP with Ctrl+Shift, the SEGV happens.
I added the following debug flags in mingw-spice-gtk.spec but cannot get the stacks:
+%global optflags -g
+%global __os_install_post :
I mean when IME is switched, WM_INPUTLANGCHANGE is called in gdk_event_translate().
But ImmDisableIME.patch can disable to switch IMEs and WM_INPUTLANGCHANGE is not called in gdk_event_translate() and SEGV does not happen.

Please note the internal ImmDisableIME.patch needs to be disabled to get the
WM_INPUTLANGCHANGE signal with mouse but no ImmDisableIME.patch causes a
SEGV with Ctrl+Shift or Alt+Shift.
Is not clear what you are suggesting with this.
Should ImmDisableIME.patch be used or not? Why it SEGV?
How do you capture WM_INPUTLANGCHANGE message?

Zenkaku_Hankaku key has the different virtual-key codes between WM_KEYDOWN

The fix is to get the scancode from virtual-key code of WM_KEYUP
(VK_DBE_SBCSCHAR) and Zenkaku_Hankaku key works fine.
Alt + Zenkaku_Hankaku key also has the different virtual-key code and
MapVirtualKey() cannot get the scancode from the virtual-key and
spice-gtk didn't send the key press events and Alt+Zenkaku_Hankaku
could not be used.
The fix is to get the scancode from virtual-key code of Zenkaku_Hankaku key
(VK_DBE_SBCSCHAR).
VK_CAPITAL, VK_DBE_ROMAN are also applied the similar fixes.
