Question: Weird artefacts on texts


I recently upgraded to High Sierra and noticed weird artefacts around texts. Here's an example:

'Use LCD font smoothing when available' is active. If I uncheck it, the weird artefacts are gone but the text becomes unreadable:

I have not noticed something like this on Sierra and I'm interested to know if it's indeed a problem or just specific to my machine.

Thank you!

Does this happen everywhere?

Your example shows a particularly difficult background that contrasts very little with the black text. With a usual whitish background does it show a problem? Just in the Finder, or other applications?

Also, what is your mac model? Retina or not?

Initially, I noticed this flickering on Safari but I haven't seen it again, presumable because of update. I have not noticed any other quirks yet but it indeed struggles on bad contrast.

My machine is MacBook Pro with Retina display, macOS High Sierra (10.13.4). The display has been replaced due to display problem.

Is this indeed a 'glitch' or something I don't need to worry about?
