Release Date: 2026-04-17
QuickView v5.2.2 is an emergency maintenance release focusing on performance reliability, security software compatibility, and Titan engine stability.
We have completely refactored our self-registration and update-checking mechanism to eliminate false positives in Microsoft Defender and other AV software.
- Idempotent Registration: QuickView now uses an O(1) INI-based check to verify registration status at startup, bypassing redundant registry operations.
- Idle Maintenance: Heavy registry updates are now deferred to a background task that only triggers when the system is truly idle.
- Animation Fast-Scan: Restored high-performance static viewing for PNG, GIF, and JXL by implementing a "magic-byte" pre-scanner that identifies static files before they enter the animation engine, avoiding unnecessary CPU overhead.
- Unified Decoding Pipeline: Consolidated various decoding paths into a robust
LoadBufferUnifiedmodel, improving memory management for massive images.
- Context Menu Fix: Resolved a regression where the context menu could appear empty when prefetching massive images in Titan mode.
- MMF Animation Probe: Fixed an issue where large animated WebP files (MMF-based) would occasionally fail to play correctly.
- Idle-Based Prefetch Trigger: Replaced fixed startup timers with a robust 500ms continuous idle detection system, ensuring prefetch tasks don't compete with the initial image load.
- Startup Resilience: Fixed a rare race condition and deadlock when opening massive files as the very first action after installation.
- HDR Accuracy: Improved peak luminance detection and tone mapping for monitors with incomplete WinRT Advanced Color reporting.
