Hey,
I have looked into the problem of the horizontal stretch, and have found it to be even more perplexing. I took some screenshots so I could post them, but when I looked at them, they were normal. I have the same video driver that I have been using since this laptop came out (2006), and have seen no other aberrations with anything else.
As a side note, there are also strange jumps in the screen, like when something produces a static interference. In one screen, I was able to see that the screen itself was doing something like a phase shift. I tried to use the fix for the MS15-097 update, which suggests turn on the service for the secdrv.sys driver. That had no effect. Not surprising though, it is mainly for if the game will not run. I had the problem with Age Of Mythology, which I still sometimes play.
Because all of this is new, I am suspecting it might still be related to an update breaking something. I have kept the Windows 10 updates from installing, as they do not update anything except make your computer vulnerable to being invaded by Windows 10. I am thinking of just doing a flat install of Vista and keeping the computer segregated from the internet.
As always,
