I create a box and add radial, I rotate and clone several times. I add news cubes and join all the elements.
I try to box trim and the web left frozen and restart Safari.
Also, now, each time I capture the screen on the web demo, Safari left frozen and restart.
I think you simply ran out of memory.
Safari on iOS has a 500MB limit (per page I guess).
As for the screen thing it’s a known issue, but to me it’s a Safari bug.
Normally a web page shouldn’t be able to freeze Safari (especially for a feature not handled by the page itself)
About Safari, on the last web demo versions I could capture and continue working, for that I report you, but could be due the las iOS update too.
