hi. i have a strange issue where requesting a focus on a text view causes 100% cpu load.
here is the code part that causes it:

ChatAppWithScaffold(focusRequester = focusRequester, contactList = contacts, ui_scale = ui_scale)
//LaunchedEffect(contacts.selectedContactPubkey) {
//    focusRequester.requestFocus()
//}

if i comment out the part as shown above. the cpu load is gone. but i want my text input box to have focus.
any ideas what i am doing wrong?
why can't i simply set a text input to have focus without this hack anyway?
any help please

Can you give us a reproducer?

[Zoff]

not sure i can. is there a debug mode where i can get logging what compose does internally? and what causes recompositions and such?

[Zoff]

but that particular issue does not seem to be recomposition.

my app is opensource. so you can try it. but since its a chat app you would need to add someone to get to the messages screen

anything i can do here?

A reproducer of the issue in as small piece of code as possible would really help.

[Alexander Maryanovsky]

Try removing portions of your code until the bug stops reproducing.

//LaunchedEffect(contacts.selectedContactPubkey) {
//    focusRequester.requestFocus()
//}

if i comment this out, like this. then the issue goes aways

i try to make a small reproducer on the weekend. but i fear it might not show the issue. is there a ways to enable logging of what compose is doing internally, to see where it burns the cpu?

[Alexander Maryanovsky]

Not really

would be nice to have in the future. to see what is happening and what is triggering component updates and such
