Weird o happens on this computer, on Chrome.
Weird o does not happen on this computer, on Firefox.
Weird o does not happen on this computer, on Internet explorer. (Though simply opening IE probably gave me tetanus.)
1920 x 1080 Resolution.
On Chrome, weird o disappears when I change the size of the font. Whether I make the font bigger or smaller doesn't matter. It only appears for me when the font is exactly that size.
If you have Weird o, change your font size to see if it stops. (No, I'm not saying that's the solution, I'm asking if the problem persists when you do.)
Will check my laptop to see if it has same issue.
