I am trying out the spring theme because I like the customizability of the html files. However I'm getting strange behavior. I just created an enterprise project and set it to spring theme. I added one dialog with the html shown in the AI tutorial, then built and ran the project. In general it seems to work, but randomly the dialog other than the header is just gray with nothing on it. If I mouse over where the buttons are then part of it shows up but the rest is still gray. Here is a screen video of it:

Can anyone tell me why this is acting this way or what I can do about it?
