Thank you for your time.
I finaly found whats wrong.
I have "Visual="Material" on the xaml.
That was causing the strange behaviour.
Altough,is this normal ? Even if a xaml contains "Visual="Material"

We understand your concern and we will try to handle it in our source level.
However, SfTextInputLayout is designed considering material design by default and we kindly request you to not to set the “Visual” property.
Please let us know if you need any further assistance.
