Marlin 2.0.9.3 and Anet A8 2004 LCD (no replies)

Hi.
I have Anet A8 with Tatara Hayabusa frame, Mega 2560 and RAMPS 1.6
I had Marlin 1.9.9 that was working fine, but I changed my hotbed to bit larger one and had to adjust few options.
As there is newer version I decided I want to upload newest one.
Downloaded source from github, made necessary changes and uploaded to machine.
Now, printer works, but I have garbage on screen instead of status screen (see attachment).
When printer starts - Marlin logo is shown correctly. When homing fails - text saying that show fine.
I tried changing everything related to status screen in source but no change - still as shown in picture.
When pressing buttons, garbage changes a little.
Any idea what I can do?

The only warnings I get are following ones:
C:\Users\XXX\Downloads\Marlin-2.0.x\Marlin-2.0.x\Marlin\src\lcd\marlinui.cpp:1194:68: warning: integer overflow in expression [-Woverflow]
adc_other_button = HAL_ADC_RANGE * 1000 / 1024;
