This may be due to a problem with your video card driver. This issue has been known to occur in the past with "Intel HD" integrated graphics hardware. To confirm that this is the issue, try rebooting the computer in Safe mode, which will use some basic video drivers. To resolve the issue, try upgrading your video card drivers. Video drivers can be found on the manufacturer's website. If you use both integrated video (such as "Intel HD") as well as a discrete video card, check your video card control panel software (typically found in your system tray in the lower right corner) to ensure that your Bentley product is set to use the discrete video hardware.
