[PATCH v4 0/6] MR2743: comctl32/edit: Keep and draw IME composition string separate from the text.
This fixes the behavior in notepad, with Japanese ibus-mozc IME, when typing "NIHONGO-SPACE-NO", or with Korean ibus-hangul when typing "GA-NA-DA". The latter still has an issue with the last character not appearing in the a composition but I believe it is unrelated to comctl32 and will be fixed by some future imm32 changes.
-- v4: user32/edit: Delegate composition string rendering to the IME UI. user32/edit: Notify IME on position, format_rect and font changes. comctl32/edit: Delegate composition string rendering to the IME UI. comctl32/edit: Notify IME on caret position, format_rect and font changes. imm32: Use DrawTextW to wrap IME composition string. imm32: Update the IME composition window position after drawing.

I've changed the implementation to delegate the IME composition string rendering to the IME UI. Windows does the same for some IME, though not when using the Korean IME somehow. I'm not sure how the edit control decides that, but it's maybe not worth worrying too much for now, and factoring the rendering in imm32 makes the code simpler.
I have implemented a simple text wrapping support, using `DrawTextW`, which should hopefully be good enough. The display could be later improved in imm32, using uniscribe or something else, but I have no idea what would be a good choice.
The composition string is displayed on top of the edit control, and doesn't move the underlying text. This is a little bit similar to Windows, but it still looks like it manages to shift some text there, though it's not clear how and it's also not very accurate either, so hopefully also something that could be improved later.
Lastly, because imm32 is not using uniscribe, the font looks very slightly different. Again, hopefully not a big deal. I think in some cases the display is also a bit redundant with the host IME display.

Actually I misremembered, and MS Japanese IME doesn't move the edit text while compositing. It overlaps the edit control just like it's done here.

Remove the space after SetBkMode( while you're at it.

if (es->composition_len == 0){SetBkColor(dc, BkColor);SetTextColor(dc, TextColor);SetBkMode( dc, BkMode);}else{if (old_font)SelectObject(dc,old_font);if (hUnderline)DeleteObject(hUnderline);}
SetBkColor(dc, BkColor);SetTextColor(dc, TextColor);SetBkMode( dc, BkMode);
Same here.
I am having trouble using a Japanese IME. Bug 53860 is fixed by this, right? The new revision is missing a Wine-Bug.

Here we will need the name, version, and test key sequences of the Japanese IME you tested.

Sorry, misread.
The new patch is not a direct fix for the old code. It's a fix to make the edit control follow the behaviour of the MS native edit control. This structural modification will not cause the EIMES_GETCOMPSTRATONCE issue.
