Hi all, I have been trying my hands on Compose recently and stumbled upon 
TextField
API. I noticed some issue in the one of the API approach. The cursor doesn't move forward as the value gets updated. Attaching a video as reference. Its the one which accepts TextFieldValue Am I missing here something ??

It has 2 variations, One which accepts value as a String and returns String in high order function.
Copy code
@Composable
fun TextField(
    value: String,
    onValueChange: (String) -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    readOnly: Boolean = false,
    textStyle: TextStyle = LocalTextStyle.current,
    label: @Composable (() -> Unit)? = null,
    placeholder: @Composable (() -> Unit)? = null,
    leadingIcon: @Composable (() -> Unit)? = null,
    trailingIcon: @Composable (() -> Unit)? = null,
    isError: Boolean = false,
    visualTransformation: VisualTransformation = VisualTransformation.None,
    keyboardOptions: KeyboardOptions = KeyboardOptions.Default,
    keyboardActions: KeyboardActions = KeyboardActions(),
    singleLine: Boolean = false,
    maxLines: Int = Int.MAX_VALUE,
    interactionSource: MutableInteractionSource = remember { MutableInteractionSource() },
    shape: Shape =
        MaterialTheme.shapes.small.copy(bottomEnd = ZeroCornerSize, bottomStart = ZeroCornerSize),
    colors: TextFieldColors = TextFieldDefaults.textFieldColors()
) {

The second being, which accepts TextFieldValue and returns TextFieldValue in high order function.
Copy code
@Composable
fun TextField(
    value: TextFieldValue,
    onValueChange: (TextFieldValue) -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    readOnly: Boolean = false,
    textStyle: TextStyle = LocalTextStyle.current,
    label: @Composable (() -> Unit)? = null,
    placeholder: @Composable (() -> Unit)? = null,
    leadingIcon: @Composable (() -> Unit)? = null,
    trailingIcon: @Composable (() -> Unit)? = null,
    isError: Boolean = false,
    visualTransformation: VisualTransformation = VisualTransformation.None,
    keyboardOptions: KeyboardOptions = KeyboardOptions.Default,
    keyboardActions: KeyboardActions = KeyboardActions(),
    singleLine: Boolean = false,
    maxLines: Int = Int.MAX_VALUE,
    interactionSource: MutableInteractionSource = remember { MutableInteractionSource() },
    shape: Shape =
        MaterialTheme.shapes.small.copy(bottomEnd = ZeroCornerSize, bottomStart = ZeroCornerSize),
    colors: TextFieldColors = TextFieldDefaults.textFieldColors()
) {

@Rooparsh have you tried on a physical device? I've seen weirdness like this on an emulator, but never my physical device.

Yes, tried on multiple devices. Facing this issue only with TextFieldValue API. The String one is working fine.
@Colton Idle I am using 
1.0.0-beta07
compose version.
@Ian Lake can you share your insights in this?

This seems pretty important though so I would file a bug with a reproducible sample if possible to get some eyes on it.
