Root cause: lib.rs applies a Mica backdrop to the main window at startup; set_custom_chrome then stripped the frame with set_decorations(false), and Mica + frameless is a broken combination on Windows (DWM backdrop glitches the whole surface). - set_custom_chrome: clear_mica() before undecorating, re-apply_mica() when restoring the native frame; set_shadow(true) so the frameless window keeps its drop shadow + resize borders. - window-state plugin: exclude StateFlags::DECORATIONS — the chrome toggle owns the decorated flag; restoring a saved decorated=false at startup would recreate the Mica-on-frameless glitch before the web side loads. Pairs with the web-side TitleBar drag fix (explicit window_start_drag on mousedown instead of data-tauri-drag-region) in the cinny repo. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

//! P5-47 — TDS Custom Window Chrome (opt-in, runtime-reversible).
|
|
//!
|
|
//! When the user opts into custom window chrome, the web client renders its own
|
|
//! `<TitleBar/>` (folds/TDS styled) and we strip the OS-native window frame so
|
|
//! the two don't stack. This is entirely opt-in: the window is built with native
|
|
//! `decorations(true)` and only `set_custom_chrome(true)` makes it frameless, so
|
|
//! the safe default is the untouched native frame.
|
|
//!
|
|
//! Everything here goes through the cross-platform Tauri v2 window API (plus a
|
|
//! Windows-only `window_vibrancy` dance in `set_custom_chrome`, since Mica and a
|
|
//! frameless window can't coexist). Each command resolves the "main" window and
|
|
//! silently no-ops if it isn't present (e.g. during teardown); the `Result`s are
|
|
//! intentionally ignored since a failed chrome tweak should never surface as an
|
|
//! error to the user.
