Reproducible since 8.0.10 then 8.0.14.
Not reproducible in 8.0.6

Height values imprecisions, probably due to Android px to MAUI dp conversion..?

@rudyspano I ran your sample locally and I'm not seeing an infinite loop

The break point inside GridProblem_PropertyChanged never fires for me if I don't scroll the CV.

Also the Repro you've provided doesn't compile out of the box. It's missing a style, so perhaps the repro isn't correct?

@PureWeen , I have updated the sample with a Console output.
I've tested my zip, if I just do a Retore Nuget package on solution, the project runs on Android.

Don't you see a lot of call of propertychanged with values near 158 (cell HeightRequest) ?

No, the property changed event doesn't fire for me after everything has settled
