In most cases, this can be resolved by updating your graphics drivers directly from the manufacturer’s website. You might also want to clear your user settings from File > SpaceClaim Options > Advanced > Reset All User Settings. Make sure your computer is using the main graphics card for SpaceClaim. You can press F9 within SpaceClaim to check what graphics card is being used. Sometimes, especially with laptops, Windows might assign a low performance graphics setting to SpaceClaim. This problem can be corrected from the graphics card “control panel” (right-click on your main desktop background), or by installing drivers to make the PC recognize your graphics hardware.
