the current problem is that it is still operating in asynchronous mode (data-\>ime_process_vkey == 0). The imm_thread_data, ime_update related code in WINE_IME_PROCESS_KEY should be moved into WINE_IME_TO_ASCII_EX.
I would like to note a few things that came to mind:
* At this point, I do not think list_add_tail is still necessary here, but removing it would increase the scope of the changes. * When STATUS_BUFFER_TOO_SMALL is returned, macdrv_ImeToAsciiEx should not be executed again. * WM_KEYDOWN message should be generated when res == 0 && data-\>update == NULL. * IME messages should not be generated when res != 0 && data-\>update == NULL.
Here, `res` refers to `key_consumed`, not the value used in v5. I hope this avoids any confusion. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9992#note_130070
