Results only visible when rotating

I was following the cavity tutorial of OPenfoam and when I load the case in Paraview, I get to see the results only when I rotate the view. After I release my mouse button the view is still there for a second or so and then turns black. Is this normal?
How can I put it so that I get to see it all the time?

video drivers
The most common reasons I can think of is video drivers or composite desktop. (ie compiz or kde4). When I run paraFoam I have to turn off the kde4 composite (alt-shift-F12) or the display acts strange. You may try downgraded to a previous version to see if it will solve your problem.

Turning off compiz did the job for me (using Ubuntu 8.10 with ATI graphics card).

Hei phelbs

i have exactly same problem like you

after i release the mouse, the view will not stable and change to black

i use ubuntu 8.10 OpenFOAM 1.5 on my office pc. but i forgot spec of the graphic card .

but its only happen for the visualisation on the paraview, others i.e linux ubuntu VLC media player will work fine.

let me check tomorrow morning.

Under System > Preferences > Appearance > Visual Effects:
Set effects to None

This step disables the fancy desktop effects but paraview should work now. If someone knows how to activate compiz effects with a working paraview, please let me know (ATI graphic card).
