Hello.
Just to let you know about this behaviour which I noticed recently: if I have three or four arrays which I'm using to display signals in a window, when resizing that window PD freezes for a good couple of minutes. It eventually comes back but it really struggles.
I'm aware that that kind of display operations are heavy but I can't recall this behaviour from past PD versions.
I'm on 10.11.6.
Cheers, Dario
