Question: How to fix random highlighting on Application window?
I have recently had the problem where each time I bring a window for an application, for example Finder or iTunes, over to my second display, I see a mysterious blue and occasionally black highlight over various pieces of text in the window.
Here's what it looks like before I bring the window to the monitor:
Now after I move it to the other display:
As you can see, there is a highlight over all of the files within the folder.
Whenever I click the files though, the highlight disappears for that specific file.
Any help will be appreciated.
