[PD] Pd 0.52-1 - frozen dsp and gui in ubuntu 20.04

Thanks Christof and Roman for the clarification, now I understand it a
little!

You're right! I was using a 10ms delay with 512 buffer size / 3 periods on
Jack.
As soon as I changed to 12ms DSP worked normally. I used 10ms on Pd for a
long time, but it was ignored as you said, and now it has turned into my
"problem".

So, that is not a bug, but maybe this limit should be clearly stated
somewhere to avoid confusion.

Thank you all so much!
