System out of memory warning

[Paul Lenhardt]

I am using the new 3.4 version of Pixelmator Pro to try to pull topographic paths out of a GeoPDF (basically I want to pull out some of the layers as vectors). However, when using the PDF features, I constantly get memory warnings from the OS saying that Pixelmator Pro is using 90-100 GB of application memory. The GeoPDF is 12 MB in size. If I don't import the layers then everything is fine (except I cannot pull out the items I want from the PDF). If I let the application sit for a minute or so, the memory drops down to 5-30GB of application memory use. When I start navigating around or interacting with the layers, the memory spikes back up and I get memory warnings again.

I am running on a MacBook Pro with an M1 Pro with 16 GB of RAM.
