Vanishing controls


Unfortunately this is not really reproducable for me:
Sometimes when navigating around in the application parts of a control (such as a text or a ListView item) or a complete control (such as a button) are vanishing. But when I switch to another window, they are visible for a short time, just before the other window is shown.
Some additions to the things posted before: this usually starts with the bottommost and rightmost control. So if there is a text box, the text will be gone. With time is gets worse. so that if for example a pivot is placed above the text box, the text of the selected pivot node isn't visible any more.
Edit 2:
When I close the application after this behaviour is occuring, I get the following error:
exception code: 0xc0000094
exception address: 0x03fad17c
module: coredll.dll
offset: 0x0006317c
The beginning of the stack trace looks like this:
at egl.SwapBuffers(IntPtr display, IntPtr surface)
at Device.Present()
at Renderer.Render(Control collection controls)
then many things with Renderer. and at the end Program.Main()

This apparently doesn't happen while debugging with Visual Studio. I tested it for a while while debugging, and the problem doesn't show up.

Some tests with displaying the used memory and allocated controls and shapes showed, that there is no connection between used memory and this problem. But the values of allocated controls vs. allocated shapes are maybe interesting: when the problem occurs, the number of allocated shapes is sometimes lower than the number of allocated controls. Unfortunately I don't know if this is the result or the reason for this problem, because I don't know where to debug or look for errors.

could not reproduce this symptom on any of the available examples, so i asume this issue is obsolete.
