You can safely ignore this message in Chrome. In the latest version of Chrome, they've started listing out any applications that use application/global hooks, regardless of whether they're actually causing a problem or not. DisplayFusion uses hooks for features like the Multi-Monitor Taskbars and TitleBar Buttons, but it shouldn't be causing any actual issues with Chrome or other applications.

If you find that DisplayFusion is indeed causing issues with Chrome, definitely let us know and we'll be glad to look into it further.

Thanks!
