Thanks a lot, I´ll try that.

I also wonder if using flat shaded or flat shaded with wire also gets rid of the problems.

Wireframe Bounding Box OK
Shaded Bounding Box OK
Wireframe OK
Hidden Line Invisible BAD
Hidden Line Ghost BAD
Flat Shaded BAD
Flat Wire Shaded BAD
Smooth Shaded BAD
Smooth Wire Shaded BAD
VEX Shaded OK
VEX wire shaded OK

When I change the shading in viewport to “VEX Shaded” the weird geometry disappears and everything is OK. … Interesting …

thanks!

Do you think modifying my GeForce to Quadro could solve this? I guess this beast is built for these high-end cards. : )
