Problems with IE 9
Internet Explorer 9 trial run unveils a couple of hitches! Some web applications are not yet fully compatible with IE 9. I run the 64 bit edition and have come across some annoying issues, mainly with the web administrative console of WordPress, and with some scripts such as, ads that do not show up only in IE 9. In this brief article you will find two temporary workarounds that help you sort out these issues and other problems that you may be encountering.
The controls in the administrator’s console of wordpress (blog publication software) are not functioning anymore in IE 9. For instance, the hyperlink insertion or removal control does not function while editing or creating text is a nightmare. The symptoms appear to indicate that IE 9 is either blocking wordpress functionality or stripping off some commands that makes text editing useless. The resolution to this problem and related ones with other content management systems is to turn on Compatibility View from the Tools menu. By default, all bars are hidden in IE 9 and to show the command bar you need to right click the topmost row next to the websites’ tabs and select Command bar. Then from the Tools menu, select Compatibility View.
Since Internet Explorer 9 supports GPU hardware acceleration, Microsoft included a new option called Accelerated graphics. Apparently, the new accelerated graphics feature of IE 9 is causing some issues with both performance and web scripts. According to Microsoft to resolve this issue, you need to install the latest video driver that supports GPU hardware acceleration. But what if my system works fine with other browsers or even with IE 8 or previous versions?
Some websites have more complex graphics and you may notice that some graphics do not show or do not render correctly such as, advertising gadgets. 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 However, some outdated video cards and video drivers do not support GPU hardware acceleration.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.
The above mentioned issue and performance degradation can occur if Internet Explorer 9 is running in Software Rendering mode. On the other hand, forcing IE 9 to run in Software Rendering mode has a positive outcome for some websites. For the time being, it solves the rendering problem.
To determine whether Internet Explorer 9 is using Software Rendering mode, follow these steps:
- Start Internet Explorer 9.
- Click Internet Options on the Tools menu.
- On the Advanced tab, locate the Accelerated graphics section.
- 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.
