    Hi,

    when running the basicshapes-cpp example (without modification), I get some weird behavior:
    The objects are drawn in the sequence in which they were created and it seams like no depth buffer (I'm not sure how that is really called) is used. That means that regardless if it is behind another object, the last object will always be drawn on top. The same thing seems to also happen in the torus.
    Is there a way to solve this?

    I am using Qt 5.7.0 on Linux.

    regards,
    andi

      Hi! The image-upload feature on our forum is broken, you might see the picture but other users don't. Please upload your image to a image hoster of your choice (e.g. postimage.org) and embed the pic here with the following markup: ![alternate text](image-url). See also How to insert image on this forum and Hitchhiker's Visual Guide to the Qt Forum.

          What's your graphics card and driver? I've experienced similar problems with older Intel graphics.

            I have a Lenovo Laptop with an integrated graphics chip:
            Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
            I am not quite sure about the driver but I didn't modify anything in that regard from the standard ubuntu install.
            Is there anything I can do about it?

              For anyone still interested, my problem was solved by updating Qt.
