[BUG] Ender 3 v2 startup progress bar

[steljwagh]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

When #define DWIN_CREALITY_LCD_JYERSUI the Ender 3 v2 displays a weird second progress bar after startup.

I also tried #define DWIN_CREALITY_LCD_ENHANCED, then there is a screen reset issue which also causes a weird artefact after starting up, which causes every item to disappear and reappear on dialling the rotary encoder, I don't intend to use this setting but maybe it's relevant.

It doesnt seem to affect the printer's working.

I compile with the STM32F103RE_Creality(512k) environment for a BOARD_CREALITY_V427 motherboard.
During compiling I got this error:

Marlin\src\module\settings.cpp: In static member function 'static void MarlinSettings::reset()':
 3206 |   FSTR_P const hdsl = F("Hardcoded Default Settings Loaded");
      |                ^~~~

Doesnt seem to relate to the display issue, but every information could be of help :)

My DWIN_SET has been updated to the files included from the marlin configuration example repo.

Do you have the sdcard inserted? Try it without sd card inserted. then insert the sdcard after boot, do you get a new progress bar on insertion of the sdcard?

[steljwagh]

No, I don't have the sdcard inserted. When booting up the second progress bar is visible with or without the sd card inserted. When i insert the sd card after boot i do get a new progress bar on insertion of the sdcard.

That points me at #define REINIT_NOISY_LCD 1 // Have the LCD re-init on SD inserting which is what I suspected and why I asked the weird sdcard related questions

Could you try a little code change.

In Marlin/src/inc/Conditionals_post.h is

#if PIN_EXISTS(SD_DETECT) && NONE(HAS_GRAPHICAL_TFT, LCD_USE_DMA_FSMC, HAS_FSMC_GRAPHICAL_TFT, HAS_SPI_GRAPHICAL_TFT, IS_DWIN_MARLINUI, EXTENSIBLE_UI)
  #define REINIT_NOISY_LCD 1  // Have the LCD re-init on SD insertion
#endif

change this to include your DWIN_CREALITY_LCD_JYERSUI ie change to the following

#if PIN_EXISTS(SD_DETECT) && NONE(HAS_GRAPHICAL_TFT, LCD_USE_DMA_FSMC, HAS_FSMC_GRAPHICAL_TFT, HAS_SPI_GRAPHICAL_TFT, IS_DWIN_MARLINUI, EXTENSIBLE_UI, HAS_DWIN_E3V2)
  #define REINIT_NOISY_LCD 1  // Have the LCD re-init on SD insertion
#endif

This should get rid of the double progress bar

[steljwagh]

Wow, you fixed both issues.

I tried the DWIN_CREALITY_LCD_JYERSUI and the progress-bar after bootup is now gone and the display behavior is exactly as expected, also upon removal/insertion of sdcard.

I took the opportunity to also test DWIN_CREALITY_LCD_ENHANCED and the weird display glitch after bootup is also gone now.

Thank you for this fix! :)
