Main MDI Scroll Behavior (Apple)

[tresf]

On Apple only, the Main LMMS window's MDI behavior is broken when using the scrollbars.

https://github.com/LMMS/lmms/blob/stable-1.1/src/gui/MainWindow.cpp

For example, when utilizing more space than the LMMS window, scrollbars appear (this is normal). However, on Apple, the scroll bars successfully move the background wallpaper, but fail to move the foreground contents.

This behavior does not occur on other scrollbars, just the main window.

Since QT MDI windowing and Apple aren't a very common combination, I'm hoping I can get some help in terms of where to look and direction (will file bug with qt team if necessary).

If a screenshot or videos helps to explain this behavior, let me know.

I've opened a support request with the QT team on this. List archive is here:

No response from the QT team after multiple emails.
TODO:
Install QT Creator (except in OS X) to determine if this bug is specific to the LMMS codebase or not.

Somehow either a MacPorts update or the Lion build fixes this on Yosemite. Closing out for now. Stable-1.1 will have a Lion build available, or you can snag RC11 from my tresf/lmms/releases URL.
