Eliptical selection tool is making jagged selections in 1 document, why?

Hi All,

I'm stumped by this. The Eliptical selection tool is making jagged selections in just 1 document. The Anti-Alias checkbox is checked and I'm just hitting shift+F5 to fill it. Jagged fill.

Hoping you can help, screenshot attached.

Thanks 😉

John

Could you please post a meaningful screenshot taken at View > 100% with the pertinent Panels (Layers, Channels, Options Bar, …) visible? 

What is the active Layer’s Blend Mode?

A-ha!

The layer mode was 'Dissolve.'

Problem solved.

Thanks very much!

John
