Hi,
Not sure if it's a zephyr issue or a LVGL issue, so I hope I'm at the right place.
I use an 1.54 eink display with the SSD1681 driver, and LVGL. Everything goes well except that partial refresh is only triggered when a very small portion of the screen is used. I know for a fact that partial refresh on this screen works even with changing a big part of the screen, because it works with an Arduino driver, but here there is something somewhere that prevent that to happen.
Since I can partial refresh when changing only a little thing (like 1 or 2 characters), I now my device is correctly configured.
Does someone have some experience with this?
Thanks in advance.
