Desktop settings page opens slowly (~500ms) on fast hardware #467
Description
What Happened?
Clicking the Desktop plug in Switchboard takes about half a second before the UI appears. It feels like the page is building everything up front and doing blocking work (building all subpages, sync D-Bus calls, wallpaper scanning) before showing anything.
Steps to Reproduce
- Open Settings
- Click the "Desktop" settings plug
- Observe the delay before the page renders
Expected Behavior
Desktop settings should appear instantly (or close to it) on first open, without a noticeable pause.
I am not too familiar with the code, but a few hints could be to:
- Build subpages lazily: create/load each section when first selected instead of all at once.
- Make the AccountsService calls async/cached so the UI isn’t blocked by D-Bus on page load.
- Enumerate wallpapers in true async chunks and defer thumbnail work until after initial render.
