Parallels 14 Graphics/Standby Memory - W10

I have a problem where the Standby Memory increases quickly until I am out of memory. For example, if reviewing photos from camera, the previously viewed photos are shown in the Standby Memory list and the memory is not released. I'm using Windows 10.

I was going to install a Windows utility to clean the Standby Memory (such as Intelligent Standby List Cleaner by Wagnardsoft), but I was concerned that this may be related to the Parallels 14 configuration change such that system memory is used for graphics memory? (Configuration/Hardware/Graphics/Automatic (Windows will use system memory for graphics).

I would expect the Parallels use of system memory would show as "In Use" memory, so the use of these utilities would not interfere with Parallels running?
