I have a fullscreen form with aero glass enabled which is working fine until I set "IsMdiContainer" to "true". The form still has the aero effect but everything behind it is shown with an insane brightness.
Here's a picture for clarification, lower picture with "IsMdiContainer" disabled, upper one enabled: http://img521.imageshack.us/img521/4981/aeroproblem.jpg
Why's that happening and what can I do about it?
