Nextion 10.1 intelligent slow FPS?

I have been testing a simple gauge display on a 10.1 intelligent display but it seems to really slow down when I add a few elements and full screen background. Here is a video of the problem, both are using the same update commands from the microcontroller and only updating one bar and one text box, but the FPS on the second test are very bad. Is this a common problem? Is there a setting to improve the fps?

Any help would be appreciated.
