In some cases you may experience an issue with your Haestad product that occurs regardless of the model file and is found to be related to video hardware. Symptoms including the drawing pane not rendering correctly or an error or crash occurring, where the details of the error mention key phrases such as "OpenGL", "CGLDevice", "render", "GraphicsLibrary", "GLDrawing".
Example: "Feature not supported in current OpenGL version. Disable optimal image loading mode if enabled"
Example: a grayed-out screen is seen as below, whenever you create a new model or open an existing model:
The solution in this case often involves settings or drivers related to your video hardware. Meaning, the hardware on your computer that the program uses to render the drawing pane (the model plan view, including background layers). This hardware can sometimes be a discrete, separate video "card" that is more powerful for rendering 2D and 3D, or it can be onboard video hardware such as Intel HD, which resides on the CPU itself.
To resolve such issues, the best first step is usually to update your video drivers. Drivers are what your Operating System uses to interface with the hardware. If there is an issue with the driver or a compatibility problem (particularly with OpenGL), an update can often resolve the issue. One way to help prove that the video driver is the problem is to reboot the computer in Safe Mode, which will use basic video drivers. If the problem does not occur in Safe Mode, you can be more confident that the issue is with the drivers.
To check the video hardware model and driver, (Windows 7 +) right click in your desktop > Change Resolution > Advanced Settings. In the Adapter tab, you should see the video hardware model. Click Properties > Driver to check the driver date and version. To update, it is recommended that you browse to the manufacturer's website (likely either NVIDIA, AMD or Intel), find a Support or Drivers section, select the hardware model, then download and install the latest driver version. In some cases you may need to download a vendor-specific driver from the computer vendor website (such as HP or Lenovo). A reboot may be necessary after doing this.
If the latest official driver does not help, you can consider looking for and installing a beta driver version, or even rolling back to an older version as a troubleshooting step.
Another thing to check is the settings of your video hardware. These are highly dependent on the hardware but are usually located by right clicking on your desktop. For example you may see "NVIDIA Control Panel". Sometimes these can also be found in the System Tray in the lower right corner of your screen.
Note that if you use both integrated video (such as "Intel HD") as well as a discrete video card, check your video card control panel software to ensure that your Bentley product is set to use the discrete video hardware and not the "integrated" hardware.
In some cases your video hardware may still have problems rendering the drawing pane. In these cases, try toggling "Use accelerated Redraw" under Tools > Options.
In the CONNECT Edition and greater, you can edit the properties of a background image and check or uncheck the box for "Optimal image loading mode". If you encounter the following error, then unchecking the box may help, though image quality may be reduced (the background may appear blurry):
"Feature not supported in current OpenGL version. Disable optimal image loading mode if enabled"
Out of memory error when loading a background file
"Object reference " error on opening or creating model related to video drivers
