Weird behavior when animation

[vtunr]

Hi,

I'm working with TouchGFX with STM32F746BG, and I have an issue when there is animation.

You can find a video of the problem here : https://youtu.be/X-D-NkGCN5k

I also have the same issue when I add an animation between screen.

At the beginning I was working without TouchGFX (and without external ram), playing with LTDC layer, moving and everything and I no issue.

Any idea where this could come from ?

EDIT: Updated video to the right one

I'm getting a video that shows you trying to drag a slider. Is that the right video? I can't tell anything is wrong other than there is no touch registered. Does touch work generally for your board?

Switched to 16bits, working fine now.

Also some improvements come from :

• Putting framebuffer in different memory bank
• For 24 bit, setting 832 pixel wide

They are explained : https://www.st.com/content/ccc/resource/technical/document/application_note/group0/25/ca/f9/b4/ae/fc/4e/1e/DM00287603/files/DM00287603.pdf/jcr:content/translations/en.DM00287603.pdf (4.5.2, 4.5.3)
