Affinity Photo appear not to be releasing memory

[Greyfox]

Affinity Photo appears not to be releasing memory when an image file is closed, as shown in the attached video.

The video opens with Affinity Photo having just been opened, with the memory used by AP shown in Task manager as 199.7MB.
A 10,000 x 10, 000 px TIFF image is then opened which takes AP's memory use to 1,383,7MB.

That file is then closed.  I would have expected the memory used by AP to drop back to around the 200MB area, but it doesn't. It remains at 1,344.9MB

My query is whether it should be doing this,  and if not, whether it is only occurring on my system?

Intel i7-2600 CPU @3.40GHz, 16GB RAM, GTX1050ti 4GB graphics
Windows 10 (1909 build 18363.720)
Affinity Photo 1.8.0.585

Yes, it's "normal"

The Affinity Apps do not automatically release the memory used when you close a document but they will release it immediately when another program requires more memory that is currently free and available.

Thanks Carl

I have the exact same problem; and no, it seems the memory cannot be used by other software.

What problem - the OP just asked if not immediately releasing memory when an image closes is normal.  The explanatory pop-up in your screen shot needs to be read in the light of @carl123's answer above i.e. the memory's not currently available but it will be released if needed.

I've also noticed that Photo takes at least three times the memory of Photoshop CS6, when first launched and no file has been loaded. Is this normal?

Since you did not provide any detailed information (for example, what OS?, how much does CS6 take?, how much does APhoto take?), then probably no one will answer this question responsibly.

It may depend on the type of OS, but with Win it's an OS feature, not the application itself.

Mac Mojave 16 GB RAM – AP takes 504 MB, PSCS6 takes 688 MB. No open documents. Memory usage of course varies depending a lot of variables and mainly OS decides how much each app has.

Mac Pro 2013, 12-core, 64GB RAM, Mojave. Affinity Photo (current stable version) is taking 651 MB, while Photoshop CS6 is taking 195 MB.

Same for Macs. One reason is several apps may be sharing memory to hold chunks of data that several of them are using. If any of the apps could release that memory when it no longer needed that data, the others would have to reload it & performance would suffer.
