Top menu dropdown flashing on hover

Good day!

Thanks for super cool theme! It is really great and literary the only successful endeavour in this field (at least of what I know).

I fount a little problem upgrading from 5.5 to 6.3. When hovering the top menu the dropdown flashes if the mouse pointer stays near the border of hoverable element. Did try to find the bug, but could not do it fast. Please, check it when you have time to work on this module.
