It looks good to me. The important thing is that in each direction (horizontal and vertical) only one or the other of the properties is enabled.

I would guess that the OS is generating a display configuration change notification when it wakes, which is causing the view to refresh its layout. You may be able to reproduce the problem if you manually change the display configuration on another, otherwise-unaffected system.

Well, I just meant change your display configuration while the program is running. For example, change the display resolution.

Not that I can think of. It may be a framework bug, although if the setup is as straightforward as you described, I would expect it to happen all the time.
