Since I switched from Win7 to Win10 yesterday, very thin strips have flickered sporadically through the image of my laptop?!
Did you reinstall all drivers?
If I want to update the drivers for the graphics card or the screen, for example, he always tells me that I already have the best version. Are there other drivers that I would have to download?
Have a look at bios or mainboard drivers from your notebook manufacturer. For example, I can run a scan on lenovo.com to check whether I have all the drivers.
For me, that was also when I switched from Windows 8.1 to 10. For me it was the resolution. Try changing them with you
