LTDC setup, glitched rendering #1596

Hello,

your LTDC setup (from fork / branch:https://github.com/fpistm/Arduino_Core_STM32/tree/LTDC_TS_TEST_1.9.0/libraries) works so far very good, I only have an issue with glitched rendering.

According lvgl/lvgl#2903, it looks it has something to do with CPU cache is not being invalidated at the right time or isn't configured correctly....

Do you have any idea, improvement/ adjustments for your LTDC files?

Thank you
