Thanks for input. I indeed attempted to change my ClearType settings. However, that only effects letter characters and unfortunately, I did not observe any changes on the display of SB Drawings. The only solution (temporarily) that I use for now is to change the browser's zooming to %80 percent on Chrome which makes drawings look really really small if not anti-aliased.
I also attempted to change Nvidia anti-aliasing settings and intel hd graphics screen resolution settings which did not help either.
Some people from tech forums on the web suggested to use CSS (or CCS) settings of the browser by using the integrated dev tools to fix the display of drawings by changing the image rendering code to " : pixelated". However I did not attempt to do such as I don't have much info about coding and I did not want to irreparably damage my browser settings.
It has indeed something to do with screen resolution/display rendering because standard settings of my older laptop showed SB Drawings crystal clear at much lower screen resolution whereas 1080p of the newer one shows them anti aliased. And the same low settings I used on my older PC now shows them completely messed up on the new one. :S
Guess I have to retain my older PC to properly browse SB and produce drawings.
