Keyboard Macro Text Input Auto-Repeats First Character

[anthony5301]

I've found a persistent keyboard input buffer corruption issue when using external keyboard macros.
The first character received from a macro becomes "stuck" and repeats for all subsequent macro inputs, even across session restarts. Only clipboard operations can reset this state.

Steps to reproduce

1. Configure a Logitech G HUB macro containing . setup xxxxx
2. Trigger the macro in WindTerm → outputs ............. (dots only)
3. Trigger another macro containing bitbake xxxxx → still outputs ............. (still dots)
4. Restart the SSH session → macro still produces dots
5. Copy any text to clipboard
6. Trigger the bitbake macro again → now outputs bbbbbbbbbbbbb (first character of new input)
7. Trigger the . setup macro → now outputs bbbbbbbbbbbbb (still stuck on 'b')
8. Copy different text again, trigger new macro with test → outputs tttt

choose "TEXT&EMOJIS"

Expected behavior

Each macro should output its complete text string without character repetition

Environment

WindTerm version: 2.7.0 on Windows
Macro tool: Logitech G HUB (Text marco)
Connection: SSH sessions to Linux servers, com port to serial device

Additional note: When the macro in Logitech G HUB is configured in Keystroke mode, the issue does not occur. It only happens when the macro is set to Text mode.
