I have a stock dell laptop with windows 10 and native driver (never updated or changed). The resolution is set to the recommended 1366X768. When I maximize a window it sets to the viewable area perfectly with no issues and when I snap to the side it takes up half the screen as expected. However, when I resize a window I am able to drag it off the screen in any direction along with my mouse pointer. I have verified there is only one monitor detected and this laptop has never been hooked up to an external monitor, tv or other device. I have checked ever imaginable setting possible and nothing fixes the issue. Does anyone have any ideas. The only thing I haven't tried is to reinstall the video driver however I don't think that is the issue as the laptop seems to know what the screen size is as it maximizes correctly.
