Hello!
First of all is the first time i am writing in this forum. I want to say this app is incredible and thanks to everyone here because this site was so util for me.
I am using this app for a year now and never I had any problems but yesterday I updated my iPad (2017 version) and script that uses Scene lib has execution problems.
Is a script to represents some figures in 3D. Previously, with iOS 10 (iOS 11 doesn't convinced me) where I wrote the code, Pythonista ran it in 60 fps and visualice correctly a cube or a piramid (depending the uncomment lines).
Now don't draw correctly the figures without change the code and runs in 14 fps.
Do anyone have any idea? Thanks in advance
