Probably related to #1332 and #14035. Android-specific and has been around for a very long time. I'm not quite sure why this isn't fixed yet as it's a glaring issue.

I Fix this by wrapping the <ScrollView> into a <Grid> Like this,

<Grid>
   <ScrollView>
    ...
  </ScrillView>
<Grid>

just stumbled into this one... it needs sorting out

This happens on ios as well. It's happening randomly.

[roman-skvortsov]

It happens for me as well. When content size of a scrollview increases (for example I added a validation messaged bound to some variable). When value of that variable changed, the bottom part of the scrollview becomes blank, and height of that blank part is the same height as new height of the validation section

I set content background to red and scrollview background to blue. The blue art supposed to contain the content, but not just being blue

The problem is weird and still actual.

I saw an advice to downgrade to version 4.8, but it does not sound like a good solution.

Any update on this?

any update?

[marciosouzajunior]

Hi guys, I wound not expect any updates on this as XF is dead and MAUI is not ready for production (it will ever be?)

Just use the last known good version or some workaround and move on.
