All software up to date. Just opening the app causes it to use over 1GB of memory. Any ideas what I can do to fix it? I have already uninstalled and installed it again.

On a M1Mac it´s for a fresh start with an A4 plus white background layer about 646MB.
@newbie user guy; please erase your serial number from the screenshot.

That's strange... In theory, an A4 document opening should be around 400MB but the memory usage may vary depending on the currently active tool or previously activated ones. We'll look into this.

newbie user guy, do you mean you see this memory usage when in the Welcome screen, with no documents open?

Yes. It gets larger when I open a document, and it will release that memory when closed. It never released the 1GB+ it uses from opening the welcome screen. If I have more than one tab I am working with it slows my mac until I force quit pixelmator.

Got it. If it's possible, could you send the last 10 documents you see in your Welcome screen to us at support@pixelmator.com? We'd try to reproduce the issue on our end. You can zip up the documents and use our upload server to share them. Thanks!

I can't share the documents as they are client related. Sorry.

I was aware of this, but it's not it. I never had any but default pointer settings.

From the article:
However, Howard Oakley points out that this leak is associated with any pointer change—such as from the arrow to the text insertion bar—so any app with frequent pointer changes, like a Web browser, will suffer from this issue.
If this is true, it would affect Pixelmator Pro even if you don’t have a custom pointer because we’ve got lots and lots of them…

Maybe this is the cause then. Horrible since it slows everything down until a reboot.

After testing for a few days what is happening is Pixelmator never release memory. It can star very low after a reboot, smallest was 47mb, but as I use it, memory usage grows and never reduces. If I force quit the app it still doesn't release it. I have to restart my MacBook in order to get the memory back.
