E-Ink display doesn't seem to work well with Zephyr's lvgl

Hi! I'm currently trying to use waveshare E-Ink display module (waveshare_epaper_gdeh029a1). First of all, I wanted to test out the lvgl by flashing the sample onto nrf52840dk. At first, the display would not do anything, then I've deleted LUTs from shield overlay and the display started to actually show what I wanted, however the partial refresh is not working as it should. It refreshes like a full refresh. Is there any way to update the display content without refreshing it every time? I've seen this video and wanted to get similar effect.
I'm using NCS v2.6.0.
