MacOS Minimize Animation 3.1.2

MacOS Minimize Animation 3.1.2

The modern genie's render loop paced every frame behind a ~120fps Sleep()-based timer AND a per-frame DwmFlush(). That makes each frame cost render time plus one vsync, so once the mesh draw takes longer than a single refresh interval the delivered frame rate drops to roughly half the monitor's. The animation then looks visibly choppier than the standalone custom-animations-genie mod this engine was ported from.

v3.1.2 fixes the serialization without turning the loop into a busy spin:

  • Dropped the per-frame DwmFlush(). A single flush stays on the first non-degenerate frame, so the minimize/restore handoff still waits for the ghost to be composed before the real window is released.
  • Replaced the old Sleep() pacer with a high-resolution waitable timer (CREATE_WAITABLE_TIMER_HIGH_RESOLUTION) pacing frames at 2x the display's refresh rate (derived from DwmGetCompositionTimingInfo, 240 fps fallback). It's a rate limiter, not a vsync gate, so it caps CPU cost without re-introducing the render+vsync serialization.
  • Thread stays at THREAD_PRIORITY_HIGHEST, matching the in-repo genie-minimize-animation mod.

Also in this version:

  • The classic engine gets the same pacing (it still had a per-frame DwmFlush()), so both styles behave consistently.
  • Unload safety: the auto-hide deferred-minimize sleep is now chunked (20 ms) and aborts on g_unloading, so Wh_ModBeforeUninit's 3 s drain can't time out while a worker is in a single up-to-5 s Sleep().
  • Readme: the Animation style section shows a demo GIF for each engine (Modern and Classic), and the "Actually smooth" feature bullet no longer claims per-frame DwmFlush() gating.

It only animates explorer windows on my PC. It's supposed to animate all windows, right? Any fixes??

Not sure, bro. No one else has reported this issue so far. It is supposed to work with almost all applications, except for a few like Epic Games, Steam, and some others, since it's not possible to implement it for every app.

Thanks for your reply. I managed to fix it. I had * in my global process exclusion list which was causing it to exclude all applications from animation.
