@adamwilson43668 - The dead pixel issue gets into which graphics you have, the Intel iGPU (CPU module) uses the main memory for holding image before sending it off to the display, the AMD GPU systems use dedicated RAM, those 4 chips on the other side of the logic board of the GPU. To help in identifying the issue you’ll need to contact an external display to see if that bad pixel issue present on it when you are in mirror mode.

As for the OS upgrade, it’s a bit of Russia roulette! As the OS installer is also expanding the discrete pieces that make up the given OS build. So a given build can have elements which are larger than the older so they can struggle passing through the additional interface the adapter creates. Some M.2 SSD’s are more sensitive as well.
Also note, you don’t need to upgrade in order. I often just go to the higher version available for the given system. When going beyond what Apple limits you to, then it makes sense to go through the releases, I even go one step further, I make a backup before I do the next release as I’ve often had to backwind after applying Apple updates, otherwise you need to wipe the drive and do a full rebuild.
