ESP32-8048S050C - Display Flickers top to bottom after touching the screen

[gathualex]

Hey, The user interface uploaded to the board has a blue background, touching any where within ESP32-8048S050C ,the screen flickers from top to bottom and the background color changes to brown colour which is not part of the UI, looks like a color inversion. I
will appreciate any leads to solving this.
Below is a video showing the error.

Unfortunately I do not own a esp32-8048S050C. You might try to lower the PCLK variable...
"'-D ST7262_PANEL_CONFIG_TIMINGS_PCLK_HZ=(12.5*1000000)'",

What version are you using? Let me know if this helps!

Hi, i solved it by adjusting the memory available from default to 128U * 1024U on lv_conf.h
/*Size of the memory available for lv_mem_alloc()` in bytes (>= 2kB)*/

#define LV_MEM_SIZE (128U * 1024U)          

/[bytes]/`
it's working fine though i have observed it flickers one in a while on its own.
