Slow app and sometimes crashed

[indomapper]

Whenever my paint.net file size get bigger, it's often pretty laggy to use paint.net. Sometimes the app even crashed. I'm not sure whether it's just because my file size is really big or if it has to do with the app. My laptop fitted the system requirements for paint.net, and I installed the app from dotPDN.

What's wrong with it?

Are you using the latest version of paint.net 5.0.6?

What size of image are you using?

 

Also, please post your Diagnostics via the cog wheel ⚙ on the right side of the canvas:

If the app is running slower when you add more layers, it's probably because you don't have enough memory to properly work with an image of that size. The minimum requirements are only for installing the app and doing basic image editing.

 

For example, if you have 4GB, you won't be able to work with huge images with a lot of layers -- it will just be way too slow.

 

This isn't a bug with Paint.NET. It's just how computers work. Even Photoshop, GIMP, or Krita will slow down and have problems if you load up images that are larger than what can be fit in RAM. The solution is generally to upgrade your PC with more RAM and a newer/faster CPU.
