Pixel 7 Pro Screen freaking out when hot

So a few months back I've acquired an pixel 7 pro (GE2AE) from ebay to daily drive GrapheneOS. Been a blast few months until the summer (Vegas Heat being between 115-120F these past few weeks) moment I step outside the screen cooks and when I was recording a live event at the speedway that I normally do with the phones in the past, it overheat and shutdown and when I powered it back on moment it gets hot, the screen will melt and if I lock the screen it will take an active of luck just to show the screen to unlock or if I put it on ice (cold air technically) to cool it down it will return functionality, but with anything white background it has noticeable graphic bleed if that makes sense where the colors will draw downwards. Is this a common problem with these phones or could this be an replacement screen not mentioned in the ebay sale?
