Bukaake v0.7.2 — Release Notes

🎯 HiDPI Snip Calibration & Fullscreen Resize Synchronization

Bukaake v0.7.2 resolves high-DPI scaling artifacts during desktop capture, eliminating coordinate drift on scaled displays (125%, 150%, 200%) and introducing dynamic viewport recalculation for the screen snipper overlay.

🚀 What's New & Fixed

1. Authoritative Native Monitor DPI Scale Factor

• Precision HiDPI Calibration: Screen capture coordinates and selection rectangles now retrieve the authoritative display scale factor directly from Rust's native monitor handle (win.current_monitor()?.scale_factor()) via ScreenCapturePayload.
• Elimination of Startup Viewport Drift: Fixed an issue where calculating the device pixel ratio from options.screenWidth / window.innerWidth yielded incorrect scaling if the hidden window had not yet expanded past its initial 680×480 standby size.
• Three-Tier DPR Fallback: ScreenSnipper now cascades gracefully: native monitor scaleFactor ➔ window.devicePixelRatio ➔ computed viewport ratio ➔ 1.0.

2. Dynamic Fullscreen Overlay Resize Handling

• Live Viewport Adaptation: Added active resize listeners to ScreenSnipper. Resizing or moving the capture overlay across displays while in Fullscreen mode immediately synchronizes physical/CSS selection bounds and updates dimension tags in real time.
• Ergonomic Snipper UI: Cleaned up button actions and state toggle transitions in capture-manager.js and screen-snipper.js while maintaining stroke-free glass aesthetics.
