In the latest artifacts #11413 the VBA issue remains.
Next, I personally built only with: * winex11: Make sure HIMC is opened before sending IME updates. * winex11: Report empty preedit string when result string is committed.
But still no luck. It looks like VBA code editor really is something special when it comes to IME. Let me know when there's anything I can do to help like providing additional logs.
