Release v3.4.0.0 — Major Audio Visualizer Performance & Stability Release · AresX0/PlatypusToolsNew

v3.4.0.0 — Major Release (February 8, 2026)

Fixed SKMaskFilter native resource leak — 20 locations leaked ~1400 native objects/sec in Klingon, ~660 in Federation, ~352 in Jedi. All now use using var for automatic disposal.
Fixed dispatcher priority inversion — Changed fullscreen spectrum data dispatch from Send to Input priority, preventing keyboard input starvation.
Thread-safe frame-skip guard — Replaced bool with Interlocked.CompareExchange to prevent race conditions between NAudio thread and UI thread.
Fixed dispatch pile-up freeze — Guard reset moved to finally block so it can never get permanently stuck.

Fixed Federation/Jedi/TimeLord/Milkdrop fullscreen switching — Mode changes now force immediate InvalidateVisual() instead of waiting for next timer tick.
Fault-tolerant cleanup — CleanupModeResources wrapped in try/catch so mode always changes even if cleanup throws.
Fixed global animation phase reset — Removed _animationPhase = 0 from TimeLord cleanup (was causing stuttering in all modes).
Protected externally driven visualizer — OnUnloaded now skips cleanup for fullscreen visualizers that are still loaded.

Exception-safe GPU rendering — OnSkiaPaintSurface renderer dispatch wrapped in try/catch to prevent WPF from permanently stopping re-renders.
Error indicator — Shows red error text instead of freezing on last frame if a mode crashes.
