New-UDDynamic sync/refresh changed?

Product: PowerShell Universal
Version: 1.4.9
Framework: 3.1.6

Not sure if this is intended behavior or a bug, but there is one change starting from framework 3.1.6 that is currently preventing me from upgrading past 3.1.5.

When using Sync-UDElement or -AutoRefresh on a New-UDDynamic component, the entire component wrapped in the dynamic seems to be being removed/readded, instead of just refreshing. I like to wrap parts of my page in a dynamic to easily refresh, but with 3.1.6+, it causes a “blinking” effect to occur when refreshing. This is especially noticeable when surfaces (cards/papers, etc.) are wrapped in the dynamic.

Here is a video of it occurring with text in a modal.
Example code:

New-UDPage -Name 'Test' -Content {
    New-UDGrid -Container -Content {
        New-UDGrid -Item -Content {
            New-UDButton -OnClick {
                Show-UDModal -MaxWidth xl -FullWidth -Content {
                    New-UDCard -Content {
                        New-UDDynamic -id 'test-dynamic' -Content {
                            New-UDTypography -Text 'This is a test modal'
                        } -AutoRefresh -AutoRefreshInterval 1
                } -Footer {
                    New-UDButton -Text 'Close' -OnClick {

Would it be possible to return to the previous behavior New-UDDynamic?

Interesting. We had an issue where components weren’t refreshing at all that were within UDDynamics so it’s likely that change that is causing this. Maybe we got a little too aggressive with how we are reloading those components . I’m sure we can fix it and will open an issue for this.

I can see in the React dev tools that it is in fact removing and adding the components again so that’s not great.
