Mozc incorrectly treats right-click combined with certain keys as a dead-key modifier under Wine

Summary

Repost from google/mozc#999, as it seems more like a Fcitx issue than a Mozc issue at this point.

Under wine, holding right click and pressing certain inputs, it will incorrectly activate a deadkey, seemingly adding punctuation as a deadkey.

The keys I've found this to be an issue with are J and - (On american keyboards, this would be /, next to the right shift button).

This interferes with games especially, as Fcitx will not pass the input onto the game itself, resulting in missed keystrokes.

Extra relevant info from the original bug report:

  • What applications this issue happens on (e.g. Chromium, gedit).
    • Wine Notepad (notepad.exe)
    • Wine Explorer.exe
    • Final Fantasy XIV Online running under Wine
  • What applications this issue does not happen on (e.g. Chromium, gedit).
    • Have not encountered this in Linux native applications (tested under Firefox, Kate, kitty, Lutris (the main app), Steam)

Steps to Reproduce

  1. Open a wine application
  2. Hold right click
  3. Type - or J. Likely easier to test with J internationally

Expected Behavior

Expected behavior

Nothing. The application should simply receive the input as expected

Environment

  • OS: Arch Linux
  • IMF: Fcitx
  • Wine - Specifically tested under Wine Notepad and the video game Final Fantasy XIV Online.
  • Native Keymap: Danish

This is actually very interesting...

The key state contains the (1<<10) bit, which is Button3Mask (Right key is "button 3"). I send that bit to xkb common, and xkb common gives me the dead key.

But it seems to be wrong as xkb map may use some of this state bit internally. XKB_STATE_NOTIFY_EVENT also not contain the button mask, so I guess that would be the expected behavior when using xkb.

For now, as a workaround before the fix is contained in the next release, I think you can do:

  1. create a new group, and set the system default layout of that group to Danish (No dead key), if you still want Danish (or whatever you think that's good for the game playing).
  2. switch to that group with super+space (default key) when you playing the game. (Hopefully you don't care about input method while playing the wine'd game :) ).
