According to the Intel website, the HD 3000/2000 Sandy Bridge graphics are not supported in Windows 10. See link below. It's the very last one listed under Intel Core Processors:

I decided to give the Windows 10 upgrade a shot on my Dell XPS 13 L321X since my Windows Update told me that my system was Windows 10 compatible. However after the upgrade I noticed the screen would become distorted intermittently.
In the meantime, I've currently disabled the graphics drivers that Windows 10 automatically assigned to my computer after the upgrade in order to prevent the screen from distorting so I could post this message. While this current graphics mode (1024x768) is not pretty, I was hoping someone @ Dell was aware of this issue and if there will be a patch/fix for this issue?
It's a bit confusing that my system was considered to be Windows 10 compatible as evidenced by the update only to find out after-the-fact that Intel specifically mentions that my particular graphics driver is not Windows 10 compatible. And since this intermittent screen distortion validates the issue at hand, I'm afraid I'll have to revert back to Windows 7.
So if anyone @ Dell knows of a possible fix, I'd appreciate it.
