Two days ago I went to Accessibility and checked the famous "Reduce Transparency" option, just to see if my Mac will run any faster, as many say. Eventually, I didn't like my Mac that way so today I decided to go back to Accessibility and uncheck "Reduce Transparency", since I wanted to restore the transparency to its default setting. The problem is that now it seems that Notification center is somehow corrupt. When I click on it to open it, it seems and feels corrupt.Sometimes, half of it is transparent and half of it is not. Sometimes the whole of it is not transparent. Some things in it highlight themselves so randomly. You can see all those things in the photos I attached to this article. Does anyone know how to fix this issue? It's pretty annoying. PS: I restarted my Mac twice just to see if it gets any better; but hell no.
