+ MultiDisplayTest
+
+
+
+
+This test is for OS X or Windows only.
+For other OSes please simply push "Pass".
+
+The test requires two-display configuration, where
+
+- 1st display is operating in HiDPI mode;
+- 2nd display is non-HiDPI.
+
+In other cases please simply push "Pass".
+
+
+To run test please push "Start".
+
+Then drag parent / child to different displays and check
+that the proper image is shown for every window
+(must be "black 1x" for non-HiDPI and "blue 2x" for HiDPI).
+
+Please try to drag both parent and child,
+do it fast several times and check if no artefacts occur.
+
+Try to switch display resolution (high to low and back).
+
+For Mac OS X please check also the behavior for
+translucent windows appearing on the 2nd (non-active) display
+and Mission Control behavior.
+
+Close the windows.
+
+In case if no issues occur please push "Pass", otherwise "Fail".
+
