The critical security update to Adobe Flash Player 10.3 has resulted in SWF content being displayed in the upper left corner of the screen in some cases.
The issues appear to be limited to Adobe Flash Player 10.3 and Internet Explorer 9. As a result, Adobe has temporarily disabled the automatic update notification for Flash Player 10.3 and Internet Explorer.
A hotfix is in the works and a new version is expected to be available next week. In the meantime, Adobe has provided the following workarounds:
"1. On some systems, you might be able to resolve this issue by updating the Intel HD Graphics drivers. It has been reported that version 188.8.131.521 and above do not display this bug. Unfortunately, some systems might require updates directly from your system manufacturer. We're working with system manufacturers to make sure they include the latest drivers in future releases.
2. You can disable hardware acceleration in Internet Explorer 9 using the instructions on this page. Please note that you should re-enable hardware acceleration once this problem has been resolved to enjoy the full benefits of hardware acceleration.
3. Use an alternate browser. All reports indicate that this issue is specific to Internet Explorer 9. You can use Firefox, Chrome, Safari, Opera, etc. with content designed for Flash Player while this issue is being resolved.
4. You can manually uninstall Flash Player 10.3 and revert back to Flash Player 10.2. While we always recommend you use the latest Flash Player for security and stability, this will get you back to your previous version."
