Testing the Release Candidate of the Univeral GUI (2025.1.13 rc1.0), certain screen seems to break. Before being aware of the actual cause, I had already created a TCP ticket, but is seems this change was the cause:

We actually do have certain screens where we claim a little vertical space to show the one Grid record, so the user is more aware what exactly he is working under. Also there is a benefit that the user can change the column order and the option to automatically scale the width of the column depending on the data, does make a nice compact way to show information.
A form is in several cases not a viable option for the way they work and the space they need.
Consistency is a factor as well in the situation where all (actual) tabs contains grid and only 1-2 are perhaps 1:1 references. Suddenly breaking the pattern to grid add/edit your data is not desirable.
In our situation it is only grid at the moment, but the idea to have a cardist popup with some fancy formatting for certain records that would end up being 1:1, would be destroyed by this change.
There are definitely situation where it probably would be an option or even better to go to a form, but please do not make this change a final solution.
