Hi Alja,

Those little ellipses scattered all over are the end-caps of the ribbon helices being drawn in the wrong place. That is a bug. You should use Help / Report a Bug to send us a report that will include your graphics driver version and operating system. I could imagine this bug happening in Chimera daily builds because I have changed the ribbon drawing code. But it is surprising to see it in the Chimera 1.6 production release. If it is in a daily build try the latest daily build. If it is in Chimera 1.6 it is most likely a graphics driver bug. You can try to update your graphics driver or use a different computer to make this image.

Hi Tom,

you're right. Sorry I haven't thought of that myself.
Here's an image.

Sending an example image might help debug this.

Dear Chimera users,

I am trying to create an image for a publication using Chimera 1.6.1.
Whenever I turn on "silhouette" dark spots appear on the screen and on the saved image. They seem totally random but they move along with the structure when rotated. When I zoom on them they look like small "umbrella-shaped" discs. The "show shadows" option is turned off.
Does anybody know what are those spots and how to get rid of them?

Thank you very much for any help.

Regards,
Alja Oblak
