bug: Linux: Spell Check enabled in Jan 0.8.3, but no text fields show spellcheck underlines

[sai-mike]

Environment

• Jan version: 0.8.3
• OS: Debian Trixie
• Desktop: LXQt
• Display server: X11
• Install type: .deb
• Launch workaround in use: WEBKIT_DISABLE_DMABUF_RENDERER=1

Problem

Spell Check is enabled in Jan settings, but deliberate misspellings are not underlined in any Jan text field tested.

Tested fields:

• Main chat prompt
• Assistant Instructions field

There are no Jan log entries containing spell.

Expected behavior

When Spell Check is enabled, deliberate misspellings should be underlined or otherwise detected in Jan text input fields.

Actual behavior

No red underline or spellcheck indication appears in any tested Jan text field.

System spellcheck works outside Jan

Enchant providers:

hunspell (Hunspell Provider)
aspell (Aspell Provider)
hspell (Hspell Provider)

Enchant test command:

printf 'sentnce\nmispelled\ncorrect\n' | enchant-2 -d en_US -l

Enchant test result:

sentnce
mispelled

Locale:

LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"

Notes

Since Enchant correctly detects misspellings outside Jan, this does not appear to be a missing dictionary or broken system spellcheck backend.

This looks more like a Jan/Tauri/WebKitGTK spellcheck integration issue on Linux, or Jan’s editable fields not enabling native spellcheck.
