Bug ID: 55440
           Summary: StarCraft 2: can no longer input Chinese via fcitx5
           Product: Wine
           Version: 8.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv

Greetings. I'm switching from Wine-staging 8.5 to Wine-staging 8.13. Then I see
that in StarCraft 2 I can no longer input Chinese into the game via fcitx 5.

In the game, I could use key shortcut to call up fcitx 5 into Chinese mode. I
press some key then I could see the word candidates in the top left corner of
the screen (not following the cursor). However if I select one of them, nothing
goes into the game's textbox.

I also tried wine notepad, I could input Chinese in it.
The Battle.net client also work.
But the actual StarCraft 2 game do not accept my input.

StarCraft 2 version 5.0.11.90136
fcitx 5 from Debian version 5.0.23-2
Wine-staging-amd64 8.13 from
https://github.com/Kron4ek/Wine-Builds/releases/tag/8.13

In fact, it's not only StarCraft 2, Diablo 4 also have such symptom. However
StarCraft 2 is a free game so it's easier to get and debug:
https://starcraft2.blizzard.com

And I read the Wine What's New and see that there are some work going into IME
recently. There is a FIXED bug report:
https://bugs.winehq.org/show_bug.cgi?id=54991 It says Wine 8.8 was working, so
I tried it, and yes in Wine 8.8 I could input in StarCraft 2 either. However
the supposed fix which was landed in Wine 8.10 did NOT fix the problem in
StarCraft 2.

I tried to get a console log. However this game need Battle.net client to
bootstrap up. If I run wine "Battle.net Launcher.exe" & > sc2log.txt" the
resulting file is empty.

Any help is appreciated.
