Process Ribbon Next Stage button hidden in Chrome

I had a Dynamics user bring up an issue where they couldnt see the 'Next Stage' button to progress

Nothing had changed, no deployments had been made and it had been working fine earlier on! Turns out, if you zoom in or out in Chrome, the button can disappear! Resetting the view back to 100% resolved this issue. Hope that saves you a bit of head scratching!
