Hey there, debracccslp.
After reviewing your post, it appears that you're seeing pixel anomalies on the screen of your MacBook Air, and we're glad to help with this.
Reset NVRAM or PRAM on your Mac -- Reset the nonvolatile random-access memory (NVRAM) using the steps in this article. See if the pixels remain.
About LCD display pixel anomalies for Apple products released in 2010 and later -- If you're still seeing the anomalies, this article provides information which can cause the issue. If they're irregularly shaped, this may indicate that there's foreign material. Using a lint free cloth, see if the pixels are removed. If they aren't, then it's trapped within the screen. You can take your MacBook Air to an Apple Authorized Service Provider or Apple Retail Store for it to be checked.
