8048S070C - esp32-smartdisplay-demo - problem with flickering

[HouseSimOn]

Hi! I cloned esp32-smartdisplay-demo repository, uncommented default_envs = esp32-8048S070C line in platform.ini and built the code. After uploading I realized that display flickers. Then I added following line at the end of setup() function: lv_obj_set_style_bg_color(lv_screen_active(), lv_color_hex(0x003a57), LV_PART_MAIN | LV_STATE_DEFAULT); just to change background color - then the flickering is better visible. The flickering is very intensive just after programming the board. After some time it's better but still visible.

I've recorded short video in slow motion.
