In an embarrassing disclosure, Adobe this week acknowledged that the latest release of its Flash Player, versions 10.3, doesn’t work properly with Internet Explorer 9 on some systems.

The bug is detailed here. The symptoms are that Flash content either doesn’t play or plays in the wrong location, typically in the top left. It might be related to your graphics adapter.:

The reports for Flash Player 10.3 indicate that systems with Intel HD Graphics adapters running Internet Explorer 9 are the systems being impacted by this particular bug. However, if you are encountering this issue and have a different configuration we’d love to hear from you. Please review the instructions on this page for details on generating the information we’ll need for further investigation.

I have seen similar symptoms on systems with high-end ATI graphics adapters, typically when a very large number of tabs are open. I’ve found in that case that killing the right process returns things to normal.

If you’re afflicted by this bug, you have a few options:

• Try updating your Intel HD Graphics drivers, using the latest version from Intel.
• Temporarily switch to another default browser.
• Disable hardware graphics acceleration and use software rendering instead, using these instructions.

I don’t recommend rolling back to an earlier Flash version. There are too many security issues in Flash 10.2.

Have you been affected by this one?
