I have a form with a panel which is used for a GL-Context (dglOpenGL).
The context is refreshed every 40 ms by a thread.
If i now resize the form, the GL-Context is hidden by the repainted Panel/Window.
How can i prevent this behaviour, so that the context is visible while resizing.
Using TOpenGLControl is not an option here as this doesn't seem to work with rendering in threads.
