MacBook Pro Mid 2012 intermittent screen issues

Below are some photos I took this morning of an issue which seems to be happening more and more often. I haven’t taken steps to fix it yet, because typically it will fix itself after being powered on for about 10 minutes. Typically after that, it will stay working for the rest of the day. Unfortunately, this has been happening almost every day now, and (at least so far) hasn’t righted itself today. I suspect there is something wrong with the display’s connection since the display clearly can function properly outside of these episodes. Has anyone seen this issue before?
