OK, though it hasn’t happened recently.

Mostly shortcut.

No, It doesn’t write the file to disk. Once I relaunch AP, I often have to work on the recovery file to get it back to the state it was in before the freeze and then re-save (which is always successful after relaunching AP). None of my files any other embedded files in them. However, they often do have duplicate pixel layers (usually of the original photo). Almost everything else are adjustment layers and masks. There are a couple of Colour Fill and (live) editable text layers.

OK, I’ll set the files to retain their Histories and wait for it to happen again.

Would a file’s History help?

Unfortunately that will be EXTREMELY difficult to record because the problem seems to occur randomly and there is never any warning signs. It might not happen at all for hours (or days) and then it will suddenly occur just once. If I did a screen recording, it will just show the Save progress bar (like in the screenshot I posted previously) and then me doing a Force Quit.

OK, sadly, the 'freeze on save' has started happening again on my Mac Pro. All the same symptoms as before.

Yes, it is a bug but your other post did not mention smaller files – only large 800MB+ files. At the same time, none of the other issues you reported were/are happening on either of my Macs that experienced the the 'freeze on save' problem. They are running perfectly fine, with no memory or drive issues. FYI: Yes, I do know how to see/check on my Mac's hardware usage (I have menu bar utilities that monitor RAM/HDD/CPU/network usage all the time).

From reading your post, I'm not sure you are experiencing the same issue as the one I had – because I never experienced the memory/drive problems you mentioned and my problem occurred with files of ALL sizes, not just large files. The example in the screenshot I posted was only around 250MB and I've had it occur on files that were less than 100MB. In every instance, my Macs (Mac Pro 6,1 and MacBook Pro) did not experience any problems running any other application at the same time and can switch back/forth between the apps without any delay or problem.

As yet, following your procedure, it has not happened again. So, hopefully, that has fixed it.

Done

Since downgrading from 1.7.2 back to 1.7.1 the save issue had resumed but, after carrying out the procedure you described, the problem has not re-surfaced again in two days (so far).

Thank you. Yes, EXACTLY the same problem.

So I have just upgraded my Affinity suite to v1.7.2 (in the hope of resolving my ‘freeze on save’ issue in AP 1.7.1), but now a new problem has problem has arisen with layer masks. If I have a group of adjustments with a layer mask applied to the group, AP 1.7.2 now masks out the base image layer (leaving the checkerboard pattern in the masked out areas) rather than only the adjustment layers within the group. Obviously this has never happened in any other version of AP that I have used so far. Has anyone else experienced this in AP 1.7.2?

Not to my knowledge. You might want to check out my post about this same issue…
