I have also experienced a similar behavior when resizing (by click+dragging with mouse) a canvas window, on macOS. 

This freezing happens only when DSP is on.

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
