Hi all,
I have a drawing bug in my app, and reduced it to a toy app. Basically, I create an NSBorderlessWindowMask type window who's content view draws a translucent rounded rect. Its only subview is an NSTextField that draws a number in a big font. When I display the window, all is well. But when I change the textfield text, or even simply remove the textfield, its old string half remains in a ghostly outline. This works in 10.9 and 10.10, but is buggy in 10.11 and 10.12. I figure it's an OS bug, but maybe the description rings any bells for anyone? Code is here is someone cares to look...:
