    Default Flash Player causes IE to flicker

    Sorry for the lengthly posting. But for completeness, here goes:

    I find that Flash Player causes IE to flicker

    The objects that show most obvious symptoms are simple flash animations. These
    simple
    animations seem to be made using the sucessive overlay of graphic blocks. Each
    overlay
    causes a brief flicker. Since these overlays need to be done in quick
    sucession to
    achive the animated effect, the flickering is very disturbing to the eye.
    Since this
    basic form of animation is found in many adverts, it is becoming very annoying.
    For an example of animated adverts see [url]http://www.nationalrail.co.uk[/url]

    More advanced flash animations (the ones that have a very smooth movement) do
    not
    flicker. This may be because they are not composed of overlayed graphics
    images.

    But there are objects that are not Macromdia Flash objects which also flash.
    Since
    these are not animated the effect is less noticable. Once again, the flicker
    happens
    when the object is updated but the update happens less frequently. Usually the
    update
    happens when the mouse moves over the object but there may be different events
    that cause
    an update.
    The Macromedia web site (by co-incidence) contains a good example of this:
    [url]http://www.macromedia.com/support/flashplayer/[/url]

    So the attribute that defines the update behaviour of the object is a crucial
    factor in whether the object flickers or not. These attributes are usually
    hidden in
    an associated style sheet (.css). The usual attribute relates to a background
    colour
    that comes into effect when a mouse hovers over a href link.
    I have html file that I have developed that demonstrates this (Flicker.htm) as
    shown in the attached code. The associated Style sheet is themes.css and it
    contains the following single line:
    a:hover{background-color: #DEF}

    I suspect that the macromedia flash objects also use these style sheet
    attributes.
    I suspect that careful adjustment of the style attributes (eg to use
    transparent background)
    may solve the problem but this is a server-side solution that does not a
    realistic solution.

    If you remove Flash Player all of the above flickering problems stop. You can
    uninstall
    Flash V8 using add/remove programs but an older version can come into
    operation. To
    completely disable flash you need to look in C:\windows\systrem\macromed\flash
    This holds the Flash player OCX control. Rename the files in here to disable
    them.

    Of course disabling flash is not a good solution because Flash is needed in
    many
    situations.
    Flash v6.0 from the archive:
    [url]http://www.macromedia.com/cfusion/knowledgebase/index.cfm?id=tn_14266[/url]
    was installed but Flicker Remains.

    A new version of Java has been installed. Problem remains.

    Display was retrned top VGA mode and NVIDIA graphics software was uninstalled.
    Flicker was
    still found with flash animated objects. New NVIDIA software installed.
    Flicker remains.

    A replacement copy of DirectX 9.0c was installed, Flicker remains

    IE6 uninstalled and re-installed. Flicker Remains

    There seems to be nothing useful in the Advanced tab of Internet Options
    There seems to be nothing useful in Control Panel | Display

    Screen update frequency seems to have no bearing on our problem.

    So my current diagnosis is as follows:
    Macromedia flash player inserts itself into the IE screen object update
    process.
    Although it only needs to do this to handle the Flash objects, non-flash
    objects
    also pass through. In our situation, some interaction between flash player
    and IE or WinME (or something) causes flash player to introduce flicker into
    the
    update process. Style attributes make the effect visible.

    There are numerious internet references to flicker on IE6 ... eg
    [url]http://www.brunildo.org/test/IEAbackima.html[/url]
    [url]http://www.fivesevensix.com/studies/ie6flicker[/url]
    If.. you have Internet Options | Temporary Internet Files | Settings | Check
    for newer versions of stored pages: Every visit to the page
    Then.. When the object is sensitive to mouse hover then the object will
    re-load itself
    and sometimes the reload causes flicker if the background or transparency is
    not set right.
    This is similar to our proble but it is NOT THE SAME PROBLEM AS OURS.

    My setup: WinME + IE6 SP1

    Sorry to get your hopes up to see a reply Winter,
    but I just want to keep this post going because I have the same problem with
    websites that use flash ads, gamespot is one for example. I also agree that
    flash is indeed the problem here, because I deleted flash, just like the OP,
    and the flickering/blinking stopped.

    It is incredibly distracting and straining to try to read a page while
    everything around the text is flickering white.

    Thanks

    No help here either, but.....

    We started having this problem about a week ago - not sure what changed to
    make it happen, but the only way we can use ie is to disable the flash plugin
    otherwise it flickers anytime flash is on a page.

    Wonder if nvidia is the suspect as we have nvidia graphics hardware too.

    I just installed Mozilla and downloaded the flash player and hey presto - no
    more flicker, so it would appear that ie is the root of the problem.

    Mozilla is not the work around of choice, but for now it will just have to do
    I suppose - would be interested to hear if anyone else figures this out though
    as would like to get my ie back up and running.

    We have just begun to notice this happening around our corp after installing
    the lastest upgrade to GoToMyPc. Only happens in IE. My IE install uses player
    v8 where my FF uses v7 and has no flicker. does anyone else have GoToMyPC that
    is experiencing this?

    I have found that by stopping and starting GoToMyPC I can stop the behavior. Although it returns upon reboot. I have place a support call with GoToMyPC. Since it appears to be clearly their issue.

    I placed a call to gotomypc and they said it is a known issue and they are working to resolve. Hopefully a patch is forthcoming.

    Hi everyone,

    Also not going to offer a solution, but I wanted to see if what we're
    experiencing is the same issue you all are talking about. I wrote a simple
    little photo rotating thing with simple mask transitions. It reads an XML file
    from the server and loads up the photos. When it was on our development servers
    internally, it worked flawlessly. Once we pushed it live, it started acting up
    in IE 6 (not in IE 5, strangely enough). The Flash will not start running until
    the mouse moves over it. It also seems to be affecting the CSS rollovers in the
    main menu at the top of the page.

    Here are some sites as a perfect example of this horribly annoying problem.
    These site are all running off the same templates. The simple little Flash
    piece I wrote is right below the menu near the top of the page.

    Here are some of the sites:
    [url]www.phoenixnewtimes.com[/url]
    [url]www.westword.com[/url]
    [url]www.miaminewtimes.com[/url]
    [url]www.newtimesbpb.com[/url]
    (there are 7 others using the same templates)

    Maybe someone will have a solution soon. We hope so. We're considering
    replacing the Flash component with a JavaScript version.

    Thanks!

    It is happening at my work also with gotomypc users but I called gotomypc and they don't know anything about it.

    We discovered what is causing the problem on our sites.

    In IE, you must be specific with the WIDTH and HEIGTH in the embed/object
    tags. If you do not set specific width and height parameters for the Flash
    object, IE starts flaking out and doesn't start up the Flash code or anything.
    It also causes problems in CSS rollovers and such.

    Thank you, Microsoft, for such a wonderful piece of junk.

    We experience the problem. IE is fine until any flash object is loaded then any
    mouse over point (hyper links even) causes what looks like screen redraw
    (flicker) to happen.

    We do not have GoToMyPC. It's a Intel video chipset (ie Not nVidia) Win XP Pro
    sp2.

    Have tried uninstalling Flash and Video card without resolution.
