Can not confirm this.

Does this happen, when you click on File > Defaults > Load Factory Settings?
Can you click on Image > Save as with empty image?

Also please check if this issue exists in development daily builds: https://builder.blender.org/download/

Today I can not reproduce it in the default scene, only in the project I've been working with when I first noticed it. Sorry. Closing.
