Hi! So I got it working. I rolled back to Windows 7, problem gone. Definatly to do with intel integrated graphics driver and windows 10 not supported by the driver as it turns out, like you just said here.
To clarify - it’s a 5 year old laptop, I don’t use the built in screen I have two monitors each attached to the two monitor sockets, one is the nvidia 525M and the second is the intel - that’s why i only had the issue on the second monitor.
