pyautogui.size() gives wrong resolution on Windows 10 laptop

[anubhav-s]

Description:

pyautogui.size(), pyautogui.position(), pyautogui.moveTo() and some more functions are giving wrong output on Windows 10 and Windows 8 laptops (I tried on Lenovo and Dell). However, things are working fine on desktops with Windows 8 and Windows 10 versions.

Python version: 2.7.12 and 2.7.11

Some preliminary research suggests that it might be the screen DPI setting.

In Windows 8, you can right-click on the desktop, select Screen Resolution, and then click "Make text and other items larger or smaller". This might be different for Windows 10, but I believe it still exists.

This changes the "effective resolution" of your screen, which is reported by the GetSystemMetrics routine (which is what pyautogui checks).

yes indeed that's it.
Put the slider to 100% to get the proper size...
Nice catch @glitchassasin

Anyway, could this be detectable? As the real resolution is different from the 'size' of the desktop?

#116 has a clever workaround for this it seems.

I've added the DPI scaling fix to 0.9.35, so hopefully this is now fixed.
