Resizing canvas with ReScale PASeq crashes SA 5.06_64bit

I use SA 5.06_64bit on a new 2020 MacBook Pro running OS Catalina 10.15.5. I understand Catalina does not play nice with SA, or other apps for that matter.

Working with SA 5.06_64bit version, I am experiencing crashes every time I try resizing the canvas with ReScale PASeq option checked to achieve hires versions of a painting.

Here are the steps executed:

1) New Source and Canvas — ( 750 px x 1000 px @ 72 dpi tif, embedded alpha channel )
2) Record PASeq ( 3 steps, SetCanvas, AutoPaint, Adaptive Filter )
3) Resize Canvas (3000 px x 4000 px @ 300 dpi, ReScale PASeq)

Then SA crashes. However it does not crash if I don't check ReScale PASeq.

This process runs without problems on my old MacBook (OS High Sierra 10.13.6)

I do have crash report if that helps.

Best regards

Normally the crash report is very useful and i'd ask for it.  But I think you are running into a bug we know about and have already fixed.  It doesn't have anything specific to o with Catalina.  Here's what i think is going on.

The problem is associated with trying to ReScale a PASeq action step that has an Ip Op action step (in your case Adaptive Filter).

So if you don't have any ip op action steps in your PASeq, then you can use the 'ReScale PASeq' check flag without a crash happening.

So the fix for this will be in the next release.

Thanks for the helpful response. Omitting the Ip Op in the PASeq allowed to ReScale the PASeq without crashing.

I also want to thank you for creating such an amazing piece of software. It provides me with countless hours of fun and amazement since version 2.

Best regards.
