Occasionally, dashboards in Dynamics CRM misbehave:
The precise cause of misalignment is not clear, probably a rogue pixel miscalculation in the layout engine, manifesting itself when top right-hand corner listview is blank and the left one has multiple pages. Not all browsers are affected either – Edge turned out to be quite resilient, unlike IE, Chrome, or Firefox. Whatever is the reason, it’s not pretty.
You may have also noticed that, regardless of the dashboard layout you choose, you end up with a single tab, restricting user’s ability to expand and collapse tabs on demand.
Under the hood, dashboards use FormXml. That means you can export the system dashboard, extract customization.xml file, and play with the form layout. The above problem, for example, can be resolved by adding a separate tab for the bottom row – that will also allow you to control tab expanded state when dashboard is loaded.
Note: the layout issue seems to have disappeared in CRM 2016 Online, one more reason to upgrade!
