PNG export issue with inversed line on vector

Hi, i have been facing this problem from my PC but not on any of my laptops, i have exported the same image on laptop and the results is fine. Here’s my problem: whenever i exported a vector, a thin inversed line appear in the middle of the vector line as if it has an outline color, notice the “l” and “p” on the title has a weird line showing, this also happen to a smaller size, whether its a font or vector. Also take a look at the bottom side of the card, small inversed line appear in a dashed manner.

everything is set on integer value as well

Does anyboy know how to fix this?
