Hi,
As i mentioned in my post, this does not happen in my laptop. Its not just a bit of pixelation, it makes some fonts unreadable and brushstrokes look too weird for me to be able to do actual artwork. This started happening a few months ago, and I had to move to a different software to do my artwork.
Even at 100% I am still able to see jagged/wavy edges which, they should not be there. See an example below.
