I couldn't compile pc_simulator with LittlevGL v5.3 so I didn't add the lv_test_canvas_2.png

How do you mean it? Why couldn't you compile it?

@kisvegabor I tried to make similar to obj_mem_leak_tester. But I got only empty canvas area. Consecutive drawings did not make.

Strange, you can open an issue to examine it.

lv_canvas_fill_polygon still not clear to me. If you comment out lv_canvas_flood_fill the bg_color parameter is not used.
