Cause

This issue can occur if Internet Explorer 9 is running in Software Rendering mode. 

By default, Internet Explorer 9 uses GPU Rendering mode. However, some outdated video cards and video drivers do not support GPU hardware acceleration. If Internet Explorer 9 determines that your current video card or video driver does not support GPU hardware acceleration, Internet Explorer 9 uses Software Rendering mode.

Resolution

Step 1: To determine whether Internet Explorer 9 is using Software Rendering mode

Follow these steps:
  1. Start Internet Explorer 9.
  2. Click Internet Options on the Tools menu.
  3. On the Advanced tab, locate the Accelerated graphics section.
  4. Verify that the Use software rendering instead of GPU rendering check box is selected.
If this option is selected, Internet Explorer 9 is running in Software Rendering mode. If the option is greyed out, your current video card or video driver does not support GPU hardware acceleration, you may try step 2 to install the latest video driver to enable this function.

Step 2: Install the latest video driver

To resolve this issue, visit your video card manufacturer website and install the latest video driver that supports GPU hardware acceleration.  

For information about how to contact the hardware manufacturer, visit the following Microsoft website:

Note If installing the latest video driver does not resolve this issue, you may have to upgrade your video card to a video card that supports GPU hardware acceleration.
