How to reduce RAM usage

Hi everyone,

What do you want to achieve?

I want to reduce LVGL RAM consumption.
LVGL uses approximately 140kB of RAM for my application (I estimate this value using esp_get_free_heap_size function). It’s a complex GUI with 16 screens and a lot of objects.
I estimate that I have to free at least 30kB.

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

I’m using ESP32-VROOM-32E module on a custom PCB
The screen is an ILI9341

What LVGL version are you using?

v8.2, stable release

What have you tried so far?

Kind regards.
