ScreenSharePickerModal now exposes Auflösung (Auto · 720p · 1080p · 1440p · 4K) and FPS (30 · 60) as separate pill rows instead of bundled quality presets — users can pick "1440p · 30 fps" or "4K · 30 fps" which the old preset list didn't surface. The underlying screenShareSettings framerateOverride slot already existed; the modal just stopped resetting it to null on every start and now plumbs the chosen FPS through to startScreenShare. Cinema-mode fullscreen on Windows had two defects: 1. Maximized → fullscreen left the taskbar drawn on top of the window because DWM kept the maximized work-area constraints. We now unmaximize first so DWM recomposes cleanly and setFullScreen actually covers the whole monitor including the taskbar strip. 2. Esc out of cinema came back as a small floating window even when the user had been maximized before clicking the Vollbild button — the unmaximize from (1) was never undone. We now memo the pre-fullscreen maximized flag per window-id and call win.maximize() once the leave-full-screen event has fired. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
