Flashing of the asterisk when using IME.
(This GIF is 109KB. If you don't need it I erase it.)
Enter the IME with "Untitled". The asterisk in the title bar flashes.
I can't check because I can't set IME in Scintilla. Perhaps the number 0 is returned during additional input. Perhaps Scintilla is returning 0 characters for each additional input.
It's because inline mode IME, switch to window mode should not has this bug.
Added a ticket at https://sourceforge.net/p/scintilla/bugs/2178/
Added a workaround in 3c42bb3bcd09b905a6c84fc2895747d683843ae4, fix this will need some complicate changes.
~~I confirmed the correct non flash asterisk.~~ (Please free to close.)
Current changes doesn't fix this, it may cause other bugs under some rarely circumstance.
I see.
Marked as fixed by e10af5ffcd7103c047f01ea155413cdf5f5ed37c, upstream Scintilla may have a different fix in the further we can switch to that at then.
