Toggling num lock or caps lock results in glitched message below password prompt

[xfzv]

% xsecurelock --version
XSecureLock - X11 screen lock utility designed for security.
Version: v1.9.0

To reproduce:

1. Run xsecurelock
2. Toggle caps lock and num lock
3. The message below password prompt is duplicated/overriden:

No issue with

% XSECURELOCK_SHOW_KEYBOARD_LAYOUT=0 xsecurelock

but the issue occurs with my usual full config that also contains XSECURELOCK_SHOW_KEYBOARD_LAYOUT=0

  XSECURELOCK_AUTH_CURSOR_BLINK=0 \
    XSECURELOCK_AUTH_FOREGROUND_COLOR="#cdd6f4" \
    XSECURELOCK_AUTH_WARNING_COLOR="#f38ba8" \
    XSECURELOCK_COMPOSITE_OBSCURER=0 \
    XSECURELOCK_DATETIME_FORMAT="%Y-%m-%d - %H:%M" \
    XSECURELOCK_DISCARD_FIRST_KEYPRESS=0 \
    XSECURELOCK_FONT="JetBrainsMono NF Medium:size=10.5" \
    XSECURELOCK_PASSWORD_PROMPT=time_hex \
    XSECURELOCK_SHOW_DATETIME=1 \
    XSECURELOCK_SHOW_HOSTNAME=0 \
    XSECURELOCK_SHOW_KEYBOARD_LAYOUT=0 \
    XSECURELOCK_SHOW_USERNAME=0 \
    xsecurelock

I guess the expected behavior would be having the message completely re-drawn every time caps lock / num lock is toggled.
