[vtk-developers] Rendering-problem: vtkCanvas don't redraw properly

[ThomasObenaus]

Hi,

I'm using VTK with Java and get some strage rendering results. Every 
time the vtkCanvas has lost focus (e.g. when pulling down a JMenu) it 
forgets to redraw properly and the whole window remains gray (see 
prob1.png). But even sometimes the content of the window (vtkCanvas) 
seems to break out of the application and overwrites even the taskbar 
(see prob2.png)!!
I get this strange behavior using VTK 5.2.1 and the new VTK 5.4 release 
under Ubuntu 8.10 on a Laptop with an Intel Mobile 945GM/GMS/GME 
graphics controller. On others PCs using Ubuntu 8.10, Windows XP and 
Windows Vista I had the same Problem. But on these ones the problem 
could be solved configuring the JVM via  -Dsun.java2d.ddoffscreen=false 
-Dsun.java2d.gdiblit=false.

Does anyone have an idea what might be the reason for the render 
problems on the laptop with Intel Mobile 945GM/GMS/GME graphics controller?

Thanks in advance,
Thomas.
