Tearing lib support for "Two non-screen-sized buffers"

Hi,

There are some open source code or example on how to use display tearing signal on a lvgl driver configurated in “Two non-screen-sized buffers” ?

In “Two non-screen-sized buffers”, the lvgl refresh the screen usually in parts, not necessarily starting at top,left(0,0), and the display tearing signal occurs at the top,left(0,0) of the screen.

Thank’s.

No one ???

Some suggestion are welcome.
