Hello fellow AP,
I was experiencing some serious crashing when trying to exit <- to the main menu. Ipad pro 12.9 2017 iOS 11. AP 22.214.171.124.
I made some adjustments in the adjustments menu, section general. I reduced the undo limit to the minimum 8 and set autosave interval also to the minimum.
After that I opened a 6000*4000 16bit rgb image.
I put every adjustment layer on top.
After that I started to add live filters.
After having all adjustment layers on there an having added six live filters the processing started to slow way down, but no crashing.
I can now easily return <- home.
Exporting or flattening this file takes longer than I was willing to wait.
After manually having merged all layers I enden up with a 280MB PSD file or 22MB JPG.
I need to experiment some more to see if this a long term solution.
Please see if this reduces the crashing in your edits as I realy look forward to seeing this program become an industry standard.
