[BUG] Ender 3 V2 Dacai Display Rendering Bugginess

[notnot-nick]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

I have tested Marlin latest release and bugfix-2.1.x.

The UI partially displays but is bugged out, however I can navigate the marlin menu.

I am using Marlin UI on an Ender 3 V2 with a V4.2.2. board and STMF103RE processor.

Creality UI is even worse as it has no text at all, but I do not have pictures of it.

Bug Timeline

Today, when I installed Marlin2.1.x

Expected behavior

The display works properly, and I see Marlin UI

Actual behavior

I see Marlin UI but it is fragmented and displayed horribly

Steps to Reproduce

1. Build Marlin (bugfix-2.1.x)
2. Flash the LCD (dacai) by the private folder in LCD_FILES
3. Flash the printer with the built marlin binary
4. Look at the screen

DACAI ✅ Creality UI ✅ MRiscoC Pro UI ✅ JyersUI ✅ MarlinUI Portrait ❌ MarlinUI Landscape Lack of support for display rotation

You CANNOT use DWIN_MARLINUI_LANDSCAPE on this display It is a limitation of the firmware in the display.

Your also holding it in Portrait mode so should be using DWIN_MARLINUI_PORTRAIT
