http://bugs.winehq.org/show_bug.cgi?id=59540 Bug ID: 59540 Summary: Wine's ImmNotifyIME implementation does not generate WM_IME_ENDCOMPOSITION when called with NI_COMPOSITIONSTR Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: imm32 Assignee: wine-bugs@list.winehq.org Reporter: teidetechconsulting@gmail.com Distribution: --- Created attachment 80581 --> http://bugs.winehq.org/attachment.cgi?id=80581 Bug Report - and hotfix to resolve issue with steam / proton Summary Wine's ImmNotifyIME implementation does not generate WM_IME_ENDCOMPOSITION when called with NI_COMPOSITIONSTR / CPS_COMPLETE. On Windows, this call completes the active composition and posts WM_IME_ENDCOMPOSITION to the associated window. On Wine, the underlying NotifyIME is a stub that returns FALSE and no composition window messages are ever posted. Any application that uses IME composition lifecycle messages (WM_IME_STARTCOMPOSITION / WM_IME_ENDCOMPOSITION) to track whether it is in text-input mode will get permanently stuck after the first text entry session, because Wine never signals the end of composition. Affected component Wine dlls/imm32 — specifically the default IME driver's NotifyIME and ImeSetActiveContext stubs, and the lack of WM_IME_COMPOSITION / WM_IME_ENDCOMPOSITION message generation in the composition lifecycle. This is an upstream Wine bug. Proton inherits it. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
