I guess the patch does not fix 1297640.
I mean whether ImmDisableIME(-1) is called or not, Zenkaku_Hankaku is sent to spice-gtk with my test.
I think the root cause is that MapVirtualKey() cannot get the scancode of the released Zenkaku_Hankaku and the remote desktop cannot receive 
I observed when the title bar of remote-viewer is focused, Zenkaku_Hankaku event is not sent without this patch.
But I guess the original submitter mistook the issue and the customer's issue would be that Zenkaku_Hankaku is not sent when the window of 
remote-viewer is focused but not the title bar.
And I asked the customers if all the problems are fixed with the patched spice-gtk and without ImmDisableIME(-1).
