Strange behavior of graph widget in 8.0.2

I’m having strange scrunching problem with a dashboard graph in 8.0.2.
Here’s a screenshot. As you can see, it scrunches the entire widget and legend into the top tiny bit of the box, making the graph illegible. If I click on the graph everything looks fine, and if I click on the bottom right resizer reverse L in edit mode, it pops to a normal, usable size immediately, but if I go to the dashboard, it’s all squished into the top tiny bits. Any thoughts on why this might be happening and how to fix it?
