Memory leak in 1.9.0

[Setebos]

When working on astrophoto stacks and then in photo persona, RAM memory is not being released after closing files. After about 2h session memory usage for empty AP program was 6.6GB. All operations where also extremely slow. To compare, after restart AP use about 300MB of RAM on my machine.

Hey Setebos,

I dropped down from 12GB to 4GB once the stack completed. Does the RAM free up when another app needs it?

I was hoping that the update from 1.9 -> 1.10 would address this.

Startup Photo memory allocation = 623.8 Megs

16 hours moderate usage memory allocation = 1,553.9 Megs (waited 1 hours after closing last file for snapshot)

I think I read (somewhere else) that Affinity only releases memory when another app needs it

You appear to be only using 59% of your total memory, which suggests no other app needs what Affinity has right now

I tend to only use AP by itself but the system slows down to the extent that when I have a tool like paint brush in use for a few minutes then when I try to change tools or move to another area of the screen then the brush will not change to the selection arrow.  I have to open another application to get the brush to disappear so that I can select a new tool or move the image so that I can work on a different area of it.

First, try switching off hardware acceleration (if it's on) in Edit > Preferences > Performance

It's been doing a few weird things on some computer configurations

OK will give it a shot.
