Description
I am using waveshare 7 inch esp32-s3 touch-screen
I have my project running. The screen and SD card both work, but when I try to do anything with the SD card, the display flickers.
I am working with PlatformIO if it’s important.
What MCU/Processor/Board and compiler are you using?
ESP32-S3
What LVGL version are you using?
8.3
What do you want to achieve?
No flicker 
What have you tried so far?
I tried implementing a file system driver and also just accessing the SD card as usual (in Arduino)
Also, I tried running the SD card code in a task on core 0/1.
