[FEATURE]:appearance.fontSize setting not applied to UI or terminal font size (v1.18.21 Linux) #44184
Closed as not planned
Description
Feature hasn't been suggested before.
- I have verified this feature I'm about to request hasn't been suggested before.
Describe the enhancement you want to request
OpenCode Desktop v1.18.21 Linux
Problem
Changing settings.v3.appearance.fontSize in the desktop settings has no visible effect on the UI font size or the embedded terminal font size. The setting is persisted correctly but not applied.
Expected behavior
The desktop UI font size should reflect the appearance.fontSize setting, and the terminal should also use the configured size.
Actual behavior
The value is persisted (confirmed via jq on ~/.config/opencode/default.dat), but the visible font size remains unchanged after relaunch.
Environment
- OpenCode Desktop: v1.18.21
- OS: Linux (Ubuntu/Debian based — please specify)
- Desktop data store:
~/.config/opencode/default.dator~/.config/opencode/
Steps to reproduce
- Open OpenCode Desktop settings
- Change
Appearance → Font Sizeto any value (e.g., 18) - Restart the app
- Observe that font size remains unchanged
Additional context
- Issue Desktop: appearance.fontSize is persisted but not applied to UI or terminal font size #24131 (v1.14.22) reported the same problem and was closed as
not_planned/ auto-closed - Issue [FEATURE]: Font size adjustment #26269 requested Ctrl++ / Ctrl+- shortcuts, also closed
- The setting exists in config schema and has a setter, but the frontend does not apply it to CSS font-size variables
- Terminal initialization uses a hard-coded
fontSize: 14
Possible workarounds (for now)
- Use OS-level Display Scaling / Zoom
- Use browser Ctrl++ / Ctrl+- if running via OpenCode web

Requesting that the existing \�ppearance.fontSize\ setting actually be applied to the UI.
Currently the value is persisted but has no visible effect:
As a result the only way to scale text is page zoom (Ctrl +/-), which enlarges the entire UI including chrome/titlebars.
Additionally, it would be great if a conversation-only font size option were considered, so chat text can be enlarged independently of the rest of the UI.
Happy to help test once a fix lands.

Thanks for the report. This was filed against OpenCode Desktop v1.18.21 (V1), and the settings/terminal code it points to is V1 code. V1 now only gets critical fixes (security, data loss, or the app being unusable), and a font size setting not applying isn't one of those, so I'm closing this. If you'd like this in OpenCode 2.0, please open a new issue for 2.0.
