After updating lvgl in my project from v6 to v7.3, I saw huge lags in refreshing the chart, when I was touching the screen -even the zones that belong to lv_scr_act()-
I found that it’s because of the whole screen refresh the lvgl tries to do. so why this whole screen refresh is happening? How can prevent this useless refreshing?
