Waveshare 2.7 inch and Pi 3B+ screen refresh rate can't be changed

Describe the bug A clear and concise description of what the bug is.

E-Ink display is updated even when no major change takes place. In my case, the up-time count simply changes. Editing config.toml to change refresh to 0.0 doesn't work, changing the value even more also yields no results.

To Reproduce Steps to reproduce the behavior:

1. Boot fresh installation of pwnagotchi 1.5.5 and observe the E-Ink display.

Expected behavior A clear and concise description of what you expected to happen.

The display refreshes for only minor updates, about every 2-3 seconds

Screenshots If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• 1.5.5
• raspbian lite pre-made image
• Pi 3B+ and Waveshare 2.7 inch display

This happens to me on a Pi4 too, it goes completely black every single time it refreshes, does that happen to you too?
