Size of fluidic player display

I created by project specifically for use on the Chromebook.  Using http://howbigismybrowser.com/, and knowing that the district will not allow the students to close the shelf, the project is sized to work perfectly for the learners.  When uploaded to AWS and tested, all looks great and functions properly.

When uploaded to Prime, the fluidic player makes the dimension and display all hinky.  Even using the "full screen" option still left part of the project off screen and I had to use the touch screen to slide the displayed content to the left to get to the continue button.

Are there specific dimensions for display in the player?
