Bug ID: 47990
           Summary: Wine64: Candidate of CJK input method is invisible on
                    macOS Catalina.
           Product: Wine
           Version: 4.18
          Hardware: x86-64
                OS: Mac OS X
            Status: NEW
          Severity: normal

Tested with wine-4.18-112-g717109ce79:
1. $ wine64 notepad
2. Switch to Chinese Pinyin input method, and try to type something

You will find that candidate didn't display, though you still can type some
Chinese characters into notepad with the input method.

I didn't see similar on macOS 10.14, so I think this is a Catalina special
issue.

This problem still exists in wine 7.2, MacOS Big Sur 11.6 and Monterey 12.1.
While troubleshooting I found one error message in Console from SCIM_Extension
as below:

warning: attempt to begin free window rendezvous for IMKUIPanel:
0x7fd166f52890 failed due to Error Domain=com.apple.ViewBridge Code=23
"(null)" UserInfo={com.apple.ViewBridge.error.hint=description not found,
com.apple.ViewBridge.error.description=NSViewBridgeHostAbsentError}

As for https://developer.apple.com/forums/thread/109319, this
"NSViewBridgeHostAbsentError" is probably the reason why candidate list can't
be displayed.

For I'm not familiar MacOS ViewBridge framework, if anyone can clarify why this
error happened?

Thanks a lot.
