Before describing the issue

Please note from the System Details pane to this post that I have the latest flash, etc.

And Windows updates,are up to date.


Issue: Scrolling distorts flash player window (Youtube, hulu, etc.)

Since: FF 13.0.1 update in June. (I posted on the issue under "badly scrambled images".)

Problem is still there with FF 14.0.1

This distortion happens:

  1. even with just starting the browser (so no bloated cache)
  2. even with just only one or two tabs open.

And since last week's update to FF 14.01, I have also detected:

Switching to the the tab with flash content will "imprint" the image from the my previous tab on to the flash player. I have to scroll or refresh to get the flash player to show its content.

FYI, none of these flash player problems occur with IE9.

The advise from a regular contributor was to turn off hardware acceleration, but these did not solve this issue.:(

Solutions suggesting disabling all the plugins etc. have not solved the problem either.

So if you can tell me some other way to solve this, I will appreciate it.

If you downgrade to Flash 10.3, does it still happen? Flash 11.3 doesn't load video in Firefox (ignore the title).

Or disable Flash Hardware acceleration.

I have not tried to go back to an older version of flash: I was not sure I could do this without exposing my computer to the vulnerabilities that the security patches in new releases fix.

If the reset and driver update does not fix the issue, maybe I should try uninstalling and clean installing Firefox.

( I do not have the other serious problems that people seem to be having with flash not loading in the latest FF. I mean I can still watch Youtube, hulu, etc.)

Thanks again.

Flash has been causing alot of weird issues lately. Using Flash 10.3 will keep you up to date with all the security fixes in 11.3, so you are safe to downgrade. Especially since you aren't having issues, if you see the issue still happens with 10.3, go ahead and upgrade back to 11.3

Ok, will try the solutions in that order and will report back.

But I think it is flash in Firefox, as this problem is not there with my IE9.

(While the IE9 32-bit has no glitches with flash, IE9 64-bit has one tiny annoyance: Watching a Youtube clip on the full screen mode shows the browser's top and bottom edges; and mousing over the player controls makes them jitter. For some reason IE9 64-bit uses the now reviled HTML5 player though I did not give permission to join the beta testing.)

Moe than you probably wanted to know.

Just so you know, the version of Flash in Firefox is totally differen than the version in IE (and chrome), so the absence of a problem in one browser doesn't mean it isn't a Flash issue.

Sorry, it took me a while to give feedback for the suggestions you have given here.

(Please refer to sidebar on the original post for system details.)

I have reset the profile and updated the Nvidia driver. The version of FF is 14.0.1. But it still scrambles the pictures.

On top of scrambling the flash content when scrolling, it has additional problems:

As you can see from the attached image, another tab's content is showing on the youtube flash player. This happens when I have paused the video even for a short time.

I have a suspicion that the combination of Flash and Firefox does some weird things to graphic processing and memory.

(I realize that IE implements Flash differently, but they seem to have this right.)

I might just have to say goodbye to Firefox for a while.
