Hello, I have an issue, i just got a new work PC and im having troubles saving PDF schematics in high quality, everytime the lines are so thick, here are examples,

 On this one i drawed a 0.18mm and 2mm line inside my drawing, i dont need a rule but those lines are clearly not 0.18mm and 2mm thick

This is clearly unaceptable, this is what i see inside my drawing and this is what i want to save
