Artifacts STM32F469 + TouchGFX4.16

[MNieb.1]

Hi

STM32CubeIDE 1.5.1

TouchGFX 4.16

STM32F4 Lib 1.25.2

FreeRTOS

So all latest.

Display: 7'' 1024x600 connected to LTDC, SDRAM IS42s16400j-7, Framebuffer set to 0xC0000000

When static picture is displayed all is fine but when I use for example swipe menu I got something like in attached picture when sliding between pages:I got something similar on STM32F746 and there switching off DMA2D fix it, but here nothing helps.

I tried single buffer, double buffer, with and without DMA2D, RGB is set to RGB565, system clock, FMC and PCLK on LCD is set to maximum and confirmed with oscilloscope.

Is there any other option I can check to fix that?

Thanks

Michal

Hi,

Does this happen to only images ? Does this happen with any kind of animation or just the swipe menu ? I do not know if it will help but could you try to enable the animation storage as well ?

Hi Romain.

It happen also when I press simple button. So looks like every time framebuffer is refreshed, When There is no interraction still picture display correct.
