Sketchup is leaving ghost lines when I move my cursor

I am trying out this tool, and I am completely unimpressed. It is not usable on my computer. This is a screenshot of what I see…

That’s a graphics card problem. You can try going to Window>Preferences>OpenGL and changing the state of Use Fast Feedback. Another thing you should do is go to the GPU manufacturer’s site, get the latest drivers for the GPU, and install them. Don’t trust Windows to tell you if the GPU drivers are up to date.

As a point of information, integrated GPUs have never been recommended for use with SketchUp.

It would help if you identify the graphics card in your profile.
