Zoom in 2D messed up screen on mac

[Anonymous]

On my coleagues macbook air (osx 10.7.4) an ArchiCAD 14 (all hotfixes) some projects started to cause strange behaviour in 2D while zooming. See the bootom of the picture. Screen get messed up and only restarting ArchiCAD helps, but only for a while. It happened on two projects, other are just fine. Any thoughts?

I got similar problem but on ACD 15 on a 2006 mac mini 10.6.

PS. how does ACD running on that MBA? smoothly?

It works ok for smaller stuff. He does mostly interior projects, many of them in 2D and smaller residental in 3D. But I would't go for medium to large 3D models on MBA.

Here are some suggestions that can help in similar display problems:

1. Turn OFF the 2D Drawing Hardware Acceleration by setting the slider to 0 in Options/ Work Environment > Advanced Redraw Options.

2. Check if your video card is in the list of the tested cards (http://archicadwiki.com/VideoCardsForArchiCAD16) and apply the latest video card driver update.

3. Delete the preferences files, that will remove all Preferences and Work environment data of ArchiCAD. Please make sure you created a backup copy from your custom Work Environment before you apply the Preferences Cleaning: http://www.archicadwiki.com/PreferencesCleaning
