Arduino Giga display, LVGL 8.3, memory usage suddenly displayed?

Dear all,
I have not realized this before, but i suddenly see in the lower left corner of my Giga display information about memory usage and fragmentation.
Very useful, but i dont have any settings in my program that generated this info. In lv_conf.h i have switched off logging.
Any idea where this info is generated and how i can switch it off.
Thanks
