🐞 Fix stutter when expanding and hiding custom notch#45
Merged
Conversation
When expanding from hidden state, the window would briefly show an intermediate frame before the animation started, causing a visual "stutter" or "false start" appearance. The fix has two parts: 1. Decouple window creation from display by adding an `orderFront` parameter to `initializeWindow()`. This allows creating the window and setting up the SwiftUI view hierarchy without immediately showing it. 2. In `showWindow()`, start with `alphaValue = 0` and fade in over 0.15s. This masks any initial frame glitches that occur when AppKit/SwiftUI first renders the window. 3. Update `_expand()` and `_compact()` to: - Create window without showing it - Start the state animation - Then show window with fade-in This ensures smooth, stutter-free animations when the notch first appears.
Fix expand/compact animation stutter on initial appearance
Add fade-out before closing window to mask any visual glitches during the closing animation. - Reduced initial wait from 0.4s to 0.25s - Added fadeOutWindow() that fades alpha to 0 over 0.15s - Window now smoothly disappears instead of abruptly closing

So, when expanding the dynamic notch, there is always a stutter that looks like it's trying to expand, and then it freezes and then fully expands. Something happens when it's collapsing. After it collapses, it looks like there's a stutter that seems as if it's not closing exactly, and then it fully closes.
