pdf is blurry on iOS physical device.

[Jibs15]

What react-native version are you using?
^0.65.1

What react-native-pdf version are you using?
^6.4.0

What platform does your issue occur on? (android/ios/both)
iOS.

Pdf with bigger size(more than 1 MB) is loaded as blur in iOS physical device. In iOS emulator and Android platform, it does become blur initially when you zoom in but withtin seconds I get clear view which is absolutely fine.
But in iOS physical device, I have to wait for 10-15 min to get clear view after I zoom in.

<Pdf maxScale={10} source={{ uri: fileUrl, cache: true }} style={styles.pdf} onError={(error) => { console.error('Unable to load pdf: ', error); }} onLoadComplete={(numberOfPages) => { console.log(numberOfPages); }} />

Thank you in advance.
