kalzium moecular editor does not work

Are you using compiz or any desktop effects? What type of videocard and drivers do you have?

yes the test has been conducted with compiz but look at the snapshot attached there is a problem with the window supposed to show the molecule.

I will try without compiz and report.

now regarding removing compiz effects that are on my desktop (I have desktop mapped on a cylinder when using Ctrl Alt along with moving mouse pointer on desktop) I wish I knew how this is supposed to be managed with KDE 4.2 because I am not sure this feature has been entirely integrated in KDE settings as on my system I still have an app called "Compiz Desktop Effects".
Regards.

ok with KDE-4.2.00 on Intrepid 64 bits without compiz kalzium works fine ; definitely all bugs that I have filed (the molecular window not displaying the selected molecule but also the display problem on top of the window) are linked to compiz interraction ; I wiil therefore file a bug for compiz.
Regards

No need, we can change the software that the bug effects from here.

Even without compiz but with "Enable desktop effect" check in KDE-settings I have display problems in molecular editor window.
Regards.

Then it is likely an issue with the 3D drivers for your videocard. What type of video card do you have?

The bug affects me too. I've muxless Intel HD 4500 + Nvidia GT 820M. I'm using only Intel driver here. Kalzium molecule editor displays nothing.

I am also having this issue. The molecule editor shows only a black window. This is my graphics card:
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)

If there is any additional information that I should supply, please let me know.

$ lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)

Note that despite the Kalzium molecule editor window showing only a black window, stand-alone Avogadro works fine.

Ubuntu 14.04 gnome flashback session using metacity.

Same behaviour, kalzium editor show a black display when load a molecule, black at all.

Bom dia, o editor molecular do kalzium não mostra as moleculas, mesmo chamando as bibliotecas do avogadro.
