QAxWidget shown off-screen with SystemAware-DPI

On Windows 8.1 or 10, in a certain situation, a QAxWidget is not drawn at the correct coordinate in a multi-monitor, multi-dpi setup. This bug is dependent on many conditions (see below).

All these conditions must exist for the bug to appear:

• The primary monitor is set at a DPI of 150% or more
• The secondary monitor is set at 100%
• The mouse pointer is on the secondary monitor when QAxWidget is first shown
• The application manifest specify </dpiAware>true</dpiAware>
  this mean "High DPI Aware" (== System Aware) but not "Per Monitor High DPI Aware"
• The "QT_AUTO_SCREEN_SCALE_FACTOR" environment variable is set to "1"

We attached a simple project to reproduce the bug and a screenshot of the result.
