[Android] Menu flashes when opening

### Current behaviour
The menu component flashes when opening the menu via `visible=true`. I think this is actually not observable in production builds (with a Samsung S21) but rather in poor performance scenarios (dev, emulator)

### Expected behaviour
The menu doesnt flash

### How to reproduce?
show a menu

### Preview
the video only shows the menu flashing once; in the actual emulator it flashes every time when the menu opens

### What have you tried so far?

[add](https://github.com/lovegaoshi/azusa-player-mobile/blob/2648f55f4cb6c6dd72433a871a63249cbed79d1e/patches/react-native-paper%2B5.14.5.patch#L9)
```
await new Promise(resolve => setTimeout(resolve, 1));
```
fixes this issue; unfortunately I learned enough from experience to know this works but cant tell why.

### Your Environment

| software | version
| --------------------- | -------
| ios | n/a
| android | 36
| react-native | 0.81.4
| react-native-paper | 5.14.5
| node | 22
| npm or yarn | yarn v4
| expo sdk | 54

まず、報告された React Native Paper 5.14.5 環境を使って Android emulator 上で visible=true によるメニューの開閉を再現し、その後 patches/react-native-paper+5.14.5.patch、特に参照されている変更を調査します。1 ms の遅延に頼るのではなく原因を確認してください。報告された低パフォーマンスのシナリオでメニューを開いたときにフラッシュしなくなれば、作業は完了です。
