I have ramps 1.4 with marlin installed on my home built printer, I have an endstop for the top and bottom of each axis and have them configured correctly to the correct pins, I have checked each one with pronterface. My printer works as far as I can tell through sending moves through pronterface however my lcd shows total gibberish on the screen. It is a reprap discount full graphic smart controller. I have this configured correctly as far as I can tell in marlin with U8glib installed.
The lcd shows correctly until i want to use it then it just randomly will go from making sense showing what its supposed to then all of a sudden it is total nonsense. The lcd and menu works sometimes and sometimes it does not. I cannot seem to find how to replicate the issue consistently other than looking away for a second and looking back. if I stare at it nothing goes wrong until the moment I glance away.

I apologize if this doesn't make sense, ive literally been banging my head on the wall trying to figure this out.
