Problems with TJC Display

[SparkyNZ]

Hi. I have a TJC4827X243 display with the rotary knob. I don't know if this is the original display that came with my Ender3V2Neo or not since it's second-hand. I tried building Marlin a few weeks back, updated the motherboard (422) firmware and then the TJC display no longer worked properly. The highlighting boxes don't disappear when the knob is turned, images are missing the text doesn't display properly.

I thought the "display assets/tjc_update.zip" I found in this repo may have helped but after a successful TJC update, I still have the same problem.

Can somebody help me fix this please? I haven't tried building the Marlin version on this repo yet (it's been a long day). Maybe that will help?

I updated my 422 firmware with Experimental-Ender3V2-422-BLTUBL-LA-MPC-20250106.bin and the display is now working fine.
