Just flashed my Ender 5 Plus with the TH3D firmware so I could add an 12864... started a print and then a few minutes later I notice this on the LCD!
How would I fix this?

Does it change when you peel off the plastic film? – fred_dot_u Sep 19 '20 at 16:01

Don't know- but it didn't change when I held my soldering gun to its head and threatened it... I'm guessing its a problem with the firmware, as opposed to it being mad about its film not being removed – – Rahman Sep 20 '20 at 02:42

There seems to be an issue with these cheap controllers with the timing.
With reference to the next reported issues:
https://github.com/MarlinFirmware/Marlin/issues/5703 https://github.com/MarlinFirmware/Marlin/issues/5720
Add these 3 lines after the #define ENDER5_PLUS in the firmware files:
#define ST7920_DELAY_1 DELAY_NS(250)
#define ST7920_DELAY_2 DELAY_NS(250)
#define ST7920_DELAY_3 DELAY_NS(250)
