Have seen that a long time ago, but our clients have noticed the issue.
As you can see below, in browser full-screen the rightest column is overlapped by the right scrollbar. Would not be an issue if there was the bottow scrollbar but that’s not the case.
There is something slightly wrong in layout calculations : either all the table columns fit entirely in the width, either the bottom scrollbar should be there.
It is prominent in our case, as we format all numbers to right alignment everywhere.
All lookup/browse screens are concerned, tested on Firefox & Chrome.
EDIT: same with a non-right aligned field like a date see below.
It happens when CUBA manages to put all columns without deciding to put bottom scrollbar
