Performance of BlurView during scroll about react-native-blur HOT 7 CLOSED

@Kureev Yeah - I think OP's issue was probably elsewhere.

from react-native-blur.

That's very interesting since that view is just a direct mapping to native version, so there should not be any performance issues as far as I am concerned.

@brentvatne, sorry for disturbing, but would you mind enlightening us on that? Can that be the case inside ScrollView?

shouldRasterizeIOS is definitely what you should be using here, if you post some code I can try to suggest where you should be using it

from react-native-blur.

Did anyone find an answer for this? I think @grabbou is right that it just uses the native blur view from iOS.

The problem is that the blur is completed on the main thread and therefore the scrolling of a table view (list view) causes some drops in frames.

Is it still an actual issue we should solve?

@Kureev I'm getting big framedrops on Android with devmode off while using BlurView inside react-native-gifted-chat. Scrolling is good until the image loads and the blur takes effect.

If I scale down the images, the performance is great, but with large images it is very slow.

I can't test a release build because of another issue at the moment.

EDIT: Sorry, please disregard this comment, my problem was related to image caching. For anyone wondering, I ended up using react-native-cachable-image to resolve the performance issues.

So if I understand correctly, it's not about our library, right? Can I close it then?
