I am facing something rather curious. I am noticing a behaviour different on the Matlab 2023a function findobj in Windows(10/11) or UNIX (Ubuntu 22).
My issue roots to the search of figures by name. In windows I use the function like this:

figHandle = findobj(groot,'Name',figName);

So providing the figName finds the figure as expected, but running the same command under Matlab 2023a UNIX version it returns empty figHandle. I use the Matlab UNIX version in my CI environment where I found the issue.

Does it rely on lower OS functions that do not behave the same? Can I overcome this issue?
