Thank you for your report.

Do you have a full example to reproduce this issue with? It is going to be hard to find this exact bug without a way to reproduce it.

This looks like an actual bug in Slint.
Maybe something related to "Row" as pointed out by the panic location.
But I can't find a way to reproduce.

@GrigoryZhimolost Could you please provide an example a bit bigger, preferably self-contained
