This is indeed an issue with 7.1 and custom Chrome themes. We'll hopefully have it fixed up for 7.2 Beta 1, but in the meantime, you can work around this by creating a Compatibility rule. On the Settings > Compatibility tab, create a rule for Chrome, and set the TitleBar Button Horizontal Offset options to something like -50

We've just released a new DisplayFusion beta version (http://www.displayfusion.com/Download/Beta/) and this issue should be all fixed up. You should now be able to remove your Chrome Compatibility rule. Please let us know if you run into any trouble after updating.

Thanks!
