Windows 11 25H2 任务栏图标点击后 IME 指示器"中"↔"X"反复切换 + 首次点击下半屏闪屏 #135
Windows 11 25H2 正式版 (build 26200.8457) 上,每次点击任务栏图标导致 IME 输入法指示器在"中"和"X"之间来回切换,且首次点击伴随下半屏瞬态闪屏(闪屏高度等于弹出面板高度)。
两个症状:
症状 A — 闪屏:每次重启后第一次点击任务栏系统图标时,屏幕下半部分(任务栏区域)闪烁一帧,闪屏垂直高度与点击后弹出的面板一致。后续点击不复现。
症状 B — IME 指示器"中"↔"X"切换:每次点击任务栏任意图标,IME 指示器在"中"和"X"之间切换一次。无论当前显示"中"还是"CH/ENG",都会统一变为"X"。传统语言栏(独立悬浮窗口)同样受影响。
关键时间线:
Hi team, could someone please help triage this issue?
It has been a week with no labels assigned. This is reproducible on Windows 11 25H2 Build 26200.8457 and affects daily workflow (IME input method toggling to "X" on every taskbar click + first-click screen flash).
Additional details:
Not caused by GPU driver (rolled back, issue persists after uninstalling Intel Graphics Software)
Not caused by third-party security software (tested with Huorong exited)
IME reset and SFC/DISM all clean
Root cause appears to be in DWM/CTF layer interaction with taskbar on 25H2
Can this be labeled for triage? Happy to provide more traces if needed.
