My programmatically-created GUI includes uibuttongroups with multi-line titles. These are defined as cell arrays of strings, and in R2012a they render just fine. We're upgrading to R2015a, and only the first lines of these titles appear. I've tried redefining them as strings with embedded char(10) characters, as multi-row string arrays, and by using sprintf with the format string '%s\n' to convert a cell array to a string. None of these attempts work; they result in either just the first line appearing or the newline is ignored. Is there a way to restore this functionality?
