Problem with drawpolygon in GUI

Hi,
I have a GUI with two axes in it where I use drawpolygon to generate a roi in one of the axes. This has worked fine in Matlab 2020a, but after upgrading to Matlab 2022a I can draw the polygon, but I can no longer modify it. I have noticed that the surf that the polygon is drawn on top of changes "resolution" - bocomes less smooth - when I start drawing and think the problem is associated with the h.draw function.
I have tried the drawpolygon in a regular figure and there is works as expected so it seems associated with the axes in the GUI.
Anyone knows how to work around?
Regards,
Christoffer

Hello Christoffer,
In order to modify the ROI polygon once you create it using “drawpolygon” function in MATLAB R2022a, you can try changing the ‘Layer’ property to ‘front’ as a workaround for the issue.
roi = drawpolygon(handles.axes,'Layer','front');
