Affinity Photo 1.9.1.979 Windows lockup

[kfriis]

Recently downloaded and installed 1.9.1.979 becomes unresponsive, when "Channel Mixer" is requested on an old jpg image scan (cropped to 2957x1873 px). Nothing shows up (e.g. the "option" is not opened up).

Memory use fixed at 915.6 MB, CPU roughly between 10-18% (total machine use <30% at between <1 GHz to < 3GHz - max CPU "Turbo umpfh" is 4.9GHz), 8CPU, 16GB, 3TB internal NvME SSD. Fully updated Windows 10 Pro 2H20 environment. Only actively used application (besides a browser in the background and the usual processes in a normal system).

Killed process after a significant amount of minutes waiting for "recovery".

Not good. Work completely lost.

Not reproducible, since steps involved cannot be recalled.

@kfriis, try disabling hardware acceleration and see if that makes a difference. If it does, can you let me know what GPU and driver version you are using?

Hi Mark Ingram

The problem is, that I cannot reproduce the error (there were many, simple steps involved, prior to the crash).

I’ve experienced a similar “sudden death” (hanging/no response, this time running full throttle) on my MacBook 13 (Intel, 4 thunderbolt ports) MacOS 11.2.3 Affinity Photo 1.9.1 (Apple App Shop). Less than an hour ago.

There were a lot of operations involved, starting with import from a 16-bit BW TIFF, masking, selecting, altering geometry, converting back to 16-bit color, with several TIFF versions exported on the way. Saving the final version (after export) locked everything, but recovery file made me loose - ahem - “only” the last 10-20 major steps and of course a lot of “fine tuning” (a bit of a problem, still).

Crash report sent to Apple.

Approach not reproducible, but this kind of behavior can be challenging in the long run.

It’s not the same steps to the “sudden death” zone, but...
