[BUG] LCD 2004 and Mightyboard showing weird characters in some menu

[chepo92]

Bug Description

I'm updating some mightyboards with stock LCD to marlin 2.0.5.3 and facing this issues:
In some points navigating the menu (eg. moving axes), there appears a weird "H" character in the LCD.

Also in some parts it shifts one char position.

My Configurations

configs.zip

Required: Please include a ZIP file containing your Configuration.h and Configuration_adv.h files.

Steps to Reproduce

1. Upload
2. Navigate through menu

Expected behavior: clear lcd without rare chars

Actual behavior: "H"

Additional Information

Did you use official marlin? The reason I ask is the bug that places the last line one char left, I remember fixing a long time ago... unless its regressed.. here #16566 Now confirmed this is still in current marlin

Yes, I used bugfix a month ago and it was still present, I haven't done much debugging/reserach on it as is not critical

Tested bugfix today, issue still present, any advice? I'm guessing is something related to LCD, timings or libraries

I'm also having #17515 with this LCD and board
