Reconnect the OHOS host publisher to the core notification dispatcher: forward the raw sender, subject, thread and message ids, use NotificationKit with localized fallback text and a START_ABILITY wantAgent, and request notification permission after the page loads.
duration_until_next_timer_update saturates an already-expired deadline instead of subtracting two Slint instants directly, which could underflow in debug builds when a timer was due.
The 16 ms frame throttle was applied to every timeout, including when no redraw was pending, so the loop still woke at ~60 Hz after the timer change. Gate the throttle on a pending redraw and on a visible surface so an idle window sleeps until the next Slint timer or the one-second fallback.
Log system-font registration time so startup work can be attributed, and add a CI check that the Slint UI and mail-renderer fallback script lists stay identical. The two collections are separate, so this catches a script being added to only one side.
A stalled compositor could keep the Slint thread blocked in poll() for a full second. Cap the wait at 250 ms, abort the unready buffer, and drop the frame so the next redraw can retry instead of writing into a buffer whose fence never signalled.
Use SlintContext::next_timer_timeout to compute the next deadline; use a one-second fallback only when there is no timer or animation. This removes the fixed 100 ms idle wake-up while keeping timers accurate.
The caret rectangle is relative to the XComponent, but the cached window origin was only read when the page appeared. After maximizing a floating 2-in-1 window, the old floating origin was still added to every cursor update, so the IME candidate stayed at the previous window position. Listen for window rect/status changes and use a zero origin for maximized or full-screen windows.
