Lv_demo_widgets memory frag

General discussion
1

every time i click “Dark” switch to change color, the memory frag becomes larger

2

memory used become lager too

3

Might it be that styles or something are initialized again? I had a problem similar with my own project though and the cause was that i initialized my styles every time i called a function, and you should only do it once i think

Are you using LVGL’s memory manager (LV_MEM_CUSTOM == 0) or your own?

5

yes，LV_MEM_CUSTOM == 0，you can try the lv_demo_widgets and see the memory changes

6

every time i change the ''Dark" switch ,memory used ang frag become larger.

I can’t reproduce this on the PC simulator after rapidly switching back and forth at least a hundred times. The memory log is below and it doesn’t look like there is a leak:
