I build Juce Demo, using Visual Studio 2008 and run Debug target under Windows 7 64-bit.
Then I run the application. Note that I am using two monitors. One is a 24" running at 1920x1200 and to the right of that is a 30" running at 2560x1600.
Action: Move the cursor from outside the Juce main application window, to just at the window resizing border.
Result: The cursor will change from an arrow to a standard windows resizing cursor. However, for the very first frame of animation when the cursor changes, instead of a correctly appearing resizing cursor, the result is a bitmap that looks like it is being read incorrectly. There is green where there should be white, and the whole thing is stretched horizontally by a factor of 3 or 4. This looks exactly like what happens when you parse RGB data in one format, using the wrong format. A split second later, the problem corrects itself.
By moving the cursor away from, and on to, the window resizing border of the main application window, and looking carefully, you can see this problem.
This is a stock build of Juce, no changes.
Note that this only happens when the Juce window is past a certain point horizontally. Usually from every side of the second screen.
Note(2) this is not reproducible in the Release build.
