Thanks to everyone who has provided information on their system and driver versions. This has helped us work on identifying a fix for the SWF rendering issue. This bug was exposed due to some changes we made to blocklist certain incompatible drivers from using hardware acceleration in Flash Player.
We have a pre-release build ready for testing, which is available in the updated technote.
We have confirmed this fixes the SWF rendering in the wrong location on the machines where we have reproduced the problem. As there are many configurations and driver combinations that we don’t have in our testing lab, your feedback is important to ensure we have a good resolution. If your system has this issue, please download the pre-release and let us know either through the bug or on the forums if it resolves the issue. Make sure you re-enable IE9 hardware acceleration when you try the player.
The issue where the SWF rendering problem re-appears after exiting full screen mode now seems to occur sporadically, so please report your system information if you still experience this problem with the pre-release build. We are working with Microsoft to determine the cause of the full screen issue.
If you encounter any new issues please also report these, along with your feedback, through the Adobe Flash Player Bug Management System. Please review the instructions on this page for details on generating the information we’ll need for further investigation.
Update 5.25.2011 Folks that still see the top-left SWF issue, please verify that your installation was successful by selecting right click on SWF content and viewing the version in the “About Flash Player…” menu item or go here.
Update 5.26.2011 We will be releasing an update next week to address both issues (top-left and in/out full screen). We also continue to follow up on reports that the pre-release build doesn’t resolve the problem on some computers. The dxdiag info is very helpful, and also please post the URL where you are experiencing these problems.
Update 5.31.11 Flash Player 10.3.181.16 has been released and is available on adobe.com and through the auto-update notification. It addresses the Intel HD graphics and Internet Explorer 9 issue.
