I noticed a regression in compose-multiplatform 1.4.0 related with scrolls on both x and y axises. I have a modifier with scrollable arguments. In compose version 1.2.2 & 1.3.1 I was able to use my touchbar to scroll in both directions simultaneously, but in 1.4.0 it is not possible anymore - only 1 direction at a time.

.scrollable(
    state = ScrollableState {
            canvasVM.offsetY += it
           it
    },
    orientation = Orientation.Vertical
)
.scrollable(
    state = ScrollableState {
        canvasVM.offsetX += it
        it
    },
    orientation = Orientation.Horizontal
)

Alexander, do you think it could be related to the changes in our fork? or is it something from the upstream?

[Ivan Matkov]

It's probably related to smooth scrolling support. I'll take a look.


Please try to disable this feature (temporary) by compose.scrolling.smooth.enabled = false system property

[Nuru Nabiyev]

I assume you meant in gradle.properties? This did not help.

[Ivan Matkov]

No, this var need to be in app runtime, not during gradle build process. Add jvmArgs("-Dcompose.scrolling.smooth.enabled=false") to your build script.

It should be something like that:

compose.desktop {
    application {
        mainClass = "MainKt"
        jvmArgs("-Dcompose.scrolling.smooth.enabled=false")

...

To check if it works you can try to read it in your main (or whatever during app run) function:

val prop = "compose.scrolling.smooth.enabled"
    println("$prop=" + System.getProperty(prop))

[Nuru Nabiyev]

I was able to set the property to false, but only through System.setProperty(prop, "false") (and logging confirmed it), but this did not help scrolling situation

By touchbar do you mean the one on old-ish macbooks?

[Alexander Maryanovsky]

Or the touchpad?

I don’t know what you mean by old 😄

[Nuru Nabiyev]

Yes sorry, touchpad

[Alexander Maryanovsky]

ok

Can you open a bug here https://github.com/JetBrains/compose-multiplatform/issues ? We’ll take it from there.

[Nuru Nabiyev]

Yes I will, thanks

[Alexander Maryanovsky]

Thanks

I added full example composable - just copypaste into your main

Found the problem, I'll prepare a fix soon. Thanks for the report
