While using background-attachment:fixed, I am finding issues with how Chrome is rendering the background image on retina screens only. Firefox and Safari work as intended. I have also noticed that I can get it to work in Chrome when I click the "Enable continuous page repainting" box in Developer Tools > Console > Rendering. This also causes severe performance issues when enabled though. The images render fine when it's changed from background-attachment:fixed to background-attachment:scroll, but then I lose the intended effect.
Any suggestions on a work around for this? Or will I have to target Chrome on retina devices and kill the functionality?
Here is a link to the problem with a screenshot:
