Hey guys, Above is my code snippet by which I am getting list of all user applications and display them using a LazyVerticalGrid. But the list grid is laggy I have tried work around and use the key to distinguish elements but the ui is still laggy while scrolling list. Can you please suggest me the solution?

First of all don’t create multiple posts for one questionnaire put longer source code snippets in the thread.

[Mr U9Q]

Alright. I get it.

[Chrimaeon]

That said, you should load the drawable off the main thread.

[Mr U9Q]

But images are not loading from internet. They are local

[Chrimaeon]

sure, but not from your app but from different packages. it’s like a fast network connection but still nothing “cached”.

[Mr U9Q]

I get it. So using a coroutine would help resolve the lag.

better use produceState like here https://github.com/chrimaeon/favorite-apps-widget/blob/792bccf240e8365be9b827fb276[…]ava/com/cmgapps/android/personalappwidget/ui/SelectAppScreen.kt

[Mr U9Q]

Thanks I have implemented it. It works better but still laggy.

https://developer.android.com/jetpack/compose/performance 😉 Try release build with R8 enabled. There is a lot of “debug code” for compose when running an debug build

[Mr U9Q]

Sure.
