Green vertical line showing in right of round displays

Description

I’m making a bsp lib for a few waveshare boards using LVGL 9.3. I keep getting this green line on the right of the round displays. Does anyone know what could be causing this?

What MCU/Processor/Board and compiler are you using?

ESP32_S3_TOUCH_AMOLED_1_43
ESP32_S3_TOUCH_AMOLED_1_75

I have the same problem with ESPhome lvgl. It is horrible…

Column 1 offset
What display drivers are you using?

Here I’m using Arduino GFX
