Recently, after an upgrade to Adobe Flash (10.2, I believe), all of the videos that I would want to watch in Firefox would exhibit the following problem:
As you can see, the screen was split vertically with a nice green bar across the middle. In both, the picture is distorted. Even at full screen, it was very much unbearable.
In resolving the issue, I tried the old standby of reinstalling the software. Full uninstall, full reinstall. No change. Several searches proved fruitless as well. But, I think I may have been searching with the wrong search terms. My first searches, I was searching for “flash broken firefox”, “video broken firefox”, and the like.
Finally, today, I did a search for “flash split video firefox” and happened upon a result in the [H]ardOCP forums that mentioned something that sounded similar to what I was experiencing. The fix? A simple setting in Flash.
- To fix the problem, right click on the video while it is playing.
- Click on settings
- Uncheck the “Hardware Acceleration” check box (like you see in the picture at right)
- Reload the page.
That’s it. Video works perfectly for me now.
