JP IMEs not working since ImGui update

[smio102]

Since the latest game patch imgui text inputs no longer have input prediction This makes typing in Japanese very hard as you can't see at all what is being typed. Using any plugin with significant text input is basically impossible for Japanese players.

We're aware and someone is looking into it, apologies. There's no Japanese person on the main dev team, so it didn't show up in our testing.

What IME are you using?

just default microsoft windows ime

edit: also happening with Google Japanese IME

The WndProc hook is changed to use DispatchMessage instead of SetWindowLongPtr to prevent a RivaTuner incompatibility crash, and it causes incompatible wParam and lParam while handling imm messages. Ex, OpenCandidate should be 0x0005 but it is 269 in the new hook, so it doesn't trigger any IME window. I don't know why and how the difference is made, I tried to upgrade my OS to 22H2 (Win11) and the OpenCandidate can be triggered, but the composition-related messages cannot be handled well still.

I released a legacy version of my IMEPlugin just now, in case anyone needs it. https://raw.githubusercontent.com/Bluefissure/IMEPlugin/legacy/repo.json

BTW the Dalamud needs to disable the IME handling or there'll be double input https://github.com/ottercorp/Dalamud/commit/0cbb5b7805a6949580d01519e37b52f27788d88d

@Soreepeong Is there anything you can do with regards to the RTSS compatibility that maintains IME message support?
