All post attachments? Or just images? Try using a different image library if one is available:

Admin CP -> Home -> Options -> Attachments -> Default Image Processor

@Jake Bunce Yes. When uploading images! I have php GD and ImageMagick PECL.
Should i install ImageMagick PECL and enable it?

 

[Jake Bunce]

Yeah, install ImageMagick and enable it in the Admin CP. It might be a problem with your image library, and changing image libraries is one way to test it.

When uploading an image as a post attachment the image library is used to resize it.
