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>
