Marlin: [1.1.9] RRD Full Graphics Smat Display shifted

[epoxi]

This is related to issue #5703 described by @lukeskymuh.
On 1.1.9 the display shows a shifted and/or random pixels. Even using the new LIGHTWEIGHT_UI feature.

On 1.1.8 the LCD works perfect.

This was tested on 2 different LCD modules from different manufacturers (some mirno PCB changes between them). Both of them works perfectly on 1.1.8 and present the same issue on 1.1.9.

I have no luck playing with the delays :(

Controller: RUMBA
LCD: RRD Full Graphics Smat Display

I had same issue with marlin 1.1.9 , and I fixed it!
My display is #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

Same problem:
Compile&upload 1.1.8 TFT OK
Compile&upload 1.1.9 TFT bad.
I tried several versions of U8glib, and clear all arduino cache libraries folder several times. i tried several arduino IDE versions.

At the end..
i edited my ultralcd_st7920_u8glib_rrd.h and edit delay times for lcd.

my current file has (lines 43 to 75)

// If you want you can define your own set of delays in Configuration.h
#define ST7920_DELAY_1 DELAY_NS(50)
#define ST7920_DELAY_2 DELAY_NS(188)
#define ST7920_DELAY_3 DELAY_NS(50)

// comented all IF

//#if F_CPU >= 20000000
//  #define CPU_ST7920_DELAY_1 DELAY_NS(0)
//  #define CPU_ST7920_DELAY_2 DELAY_NS(0)
//  #define CPU_ST7920_DELAY_3 DELAY_NS(50)
//#elif MB(3DRAG) || MB(K8200) || MB(K8400) || MB(SILVER_GATE)

//#elif F_CPU == 16000000
//  #define CPU_ST7920_DELAY_1 DELAY_NS(0)
//  #define CPU_ST7920_DELAY_2 DELAY_NS(0)
//  #define CPU_ST7920_DELAY_3 DELAY_NS(63)
//#else
//  #error "No valid condition for delays in 'ultralcd_st7920_u8glib_rrd.h'"
//#endif

Maybe your LCD need another delays.
( I saw the solution in #4994 )

Once you find some delay times that work, please close this issue.

Thank @lokus77 !!!

Those worked perfectly :D

@thinkyhead please continue closing this issue.
