3 Strange ballooning/halo effect around windows (not "blooming")?
I've had a Macbook pro brought to me with a display issue I've never seen before. Windows pop up with a strange "bubble" or "halo" around them. If you drag a window over another, this bubble moves with the top window. If you have multiple windows at a time, each has it's own bubble over the other.
Additionally, there are vertical lines that seem to permeate the entire screen except the top bar. These lines also change/move with moving windows, but aren't as rigidly attached to windows or elements in them as the bubbles are.
Photos attached.
Has anyone ever seen this before? Attempting to search this issue only results in "blooming", which this is certainly not. Would this be fixed by replacing the display, or is it caused by a faulty graphics chip or something?
Thanks for any help and advice!

Hi @erelectronics
Have you tried connecting an external monitor and see if it occurs on it?

@jayeff Yes I tried connecting external before making this post and this does not happen on any external monitor. Sorry, I forgot to include that in the original post.
I am thinking it is a previously unknown variation of the dreaded "Apple made the ribbon cables slightly too short so they wear out" issue, but just in case this was some kind of connecting problem or etc. I wanted to check if anyone else had any ideas.
