IE 9 is completely unusable for me due to video driver issues too. For the sake of conciseness, let's just say that my Reliability Score went from about 5 (due to IE 8 crashes) to 1 (due to IE 9 crashes).
I'm using a ThinkPad T400 with ATI switchable graphics. For the curious, my setup is something like this:
- ThinkPad dock
- All peripherals connected to the dock except for the webcam, which is hooked up to the left external screen
- 2 Dell LCD screens (left one via DVI and right one via VGA)
- Disabled ThinkPad screen
- MS ergo keyboard
- MS mouse
- Macally webcam
- Iomega large USB drive
I've already posted the issue to Connect:
Besides slow tab switching and green artifacts, I'm also getting:
-Constant tab hangs
-IE9 doesn't always catch crashed tabs (so I have to kill the process tree w/ Process Explorer)
-When I switch to another tab, the stuff in the previous tab continues to be displayed
-I have to force the window to be re-drawn when I go to a new website (generally by dragging IE9 off the edge of the screen and dragging it back)
-Textboxes (such as the C9 one) are extremely slow to respond to keystrokes so spelling mistakes become a frequent occurrence.
-Things that use the browser control (such as Semagic) are also a horror to use
-The vertical scrollbar does not accurately extend to the bottom of websites.
-Resizing the IE9 window occasionally causes the contents of the website to get stretched, which looks absolutely wretched with ClearType because all the subaliasing pixels get wildly contorted.
I looked for new video drivers and found this helpful little tidbit at Lenovo's site (http://www-307.ibm.com/pc/support/site.wss/MIGR-72858.html):
Windows 7: 13 Oct 2009 (8.641.1.1-090824a-089811C)
Windows Vista: 28 Apr 2009 (8.563.2.1-090401a-079160C)
Windows XP: 10 Aug 2010 (8.752-100629a-102476C)
Your eyes aren't fooling you, by the way. Windows XP has newer video drivers than Windows 7.
I would be delighted if the IE9 team could get in touch with the person who has the power to poke Lenovo firmly in the side about the issue.
If anyone wants more details/experiments/etc, fire away. I'll be uninstalling IE9 in the morning (Pacific Time).
Incidentally, if you're wondering about the IE8 crashes, the condensed version is that resetting the browser & clearing the cache, et al does not fix the problem. I haven't tried reformatting the computer yet.
Edit: New C9 bug, ahoy. Whenever I edit a post, the carriage returns double. If the powers-that-be could shrink my post back down to size, that would be wonderful.
