This issue has come up for me in the latest updates .12 and .13.
I have a file of mostly text with a couple of shapes. Before the update I would be able to preview and send the file to the laser with minimum wait time. Now, however, it takes more than 2 minutes.
Interestingly, I think I’ve found that there’s a threshold that makes a huge jump in the time to process. If I select 70% of my text (cut selected shapes turned on), then it takes the 2 minutes. But if I select 65%, then it is almost instant. There isn’t a time difference between 70% and 100% of the text selected.
I noticed that when I turn anti-aliasing off it takes much shorter, so I can do that. But is there a reason this changed? I’d prefer to leave anti-aliasing on because it does make the text easier to read and proof.
