Hello,I use the LVGL example from ESP-IDF and it displays fine without dashed lines My screen is 800x480. I have tried changing the timing, clock, double buffer, BOUNCE, flush_callback coordinates, but none of them worked.

ESP32-S3-800X480 How do I fix this? Any help is appreciated!

Hi @H-sw123,

I think it's maybe an RGB screen drift issue. Did you try to enable XIP on PSRAM ?

Hello, Thanks for your suggestion, I solved this problem later by setting ESP_PANEL_LCD_RGB_PCLK_ACTIVE_NEG to True. You can close this question. Regards!
