this bug apears only when keyshot in fullscreen. KS v3.3.33. model imported from sketchup. windows 7 x64, 8GB RAM, videocard ATI Radeon HD 3300
Edit->Preferences->Advanced, uncheck "Graphics Effects". Does that improve the view? Also make sure you have the latest video drivers from your manufacturer's website.
Please submit a ticket to support@luxion.com if the problem persists.
