Background Manager
White flashes between slides (13 posts)

    Slideshow flashes white background between transitions.

    This is apparently an issue with Firefox and JavaScript and I'm just wondering if anyone has found a fix for this, or if there is an eta for scheduled release of a fix. Thanks!

    Hi

    This should be solved in version 1.1.11 - let me know if that's the case.

    Unfortunately it didn't seem to have any effect. I've changed it back to a single image as it's a live site, but I took a 3 minute screencast so you can see the behaviour through a couple of rotations.

    I'm having a similar problem. While the image is loading in the background, the background shows completely white. Is there a way to set it to the regular background color while it's loading?

    Thanks!

    note - this only started happening after the last update. Prior to that, the background while loading was the default color.

    I have a single background image, the site loads and everything looks good.

    If I navigate to another page "sometimes" the background image flashed - perhaps a reload. And sometimes the image is solid (no flash between pages). I watched jjsararas video - my problem is not the same - I am not changing images.

    Any ideas? Thanks

    I was too fast - mostly a Chrome issue. Otherwise Background manager looks good in the other browsers -. I still need to check ie .

    @myatu & @jjsararas, I'm seein the White Flashes too. This flash seems browser dependant, for me IE & FF but not on Chrome, however, Chrome showed me what is going on (the next image coming down line-by-line) and gave me a clue to the problem and solution.

    PROBLEM: It appears that when the background slideshow advances, it executes the transition and moves on, without every bothering to intelligently check if the next image is available or not. So the transition can happen between the current image and a non-existant image which causes that "white flash". Therefore, you don't see the transition at all. This depends on the size of the images or the speed of your connection (or both) and I can imagine cases where the background manager moves-on without displaying any images if the network was slow enough or the images were big enough or both!

    SOLUTION: The right solution for this problems is 2 fold, and both these should be done to fix it properly.
    1. Obviously, Background Manager should WAIT for the next image to be FULLY downloaded & available before moving on to execute the transition, regardless of what the slideshow or transition time is set to be, as it makes no sense to display an image thats not fully downloaded in the browser cache.
    2. Background Manager should BUFFER the next & previous image immediately after the current image is shown, to minimize & possibly avoid any lag in displaying the next image when the time comes. This should slove the white flash problem for most people (NOT All). A slower connection or large image may still not give enough time for the buffer to be ready, but MAINLY, if the slideshow is showing RANDOM order of images, buffering won't have any effect (unless you can randomize before buffering instead of before display). Therefore, for these issues (the slower connection or large images or random order or any combo of these) the previos fix is REQUIRED to solve this problem gracefully for all situations.

    How soon can we get the above fixes?

    I am also getting this problem in Chrome and Safari, shame because this seemed like a great plugin. Client won't accept the flashing though and frankly I don't blame him.

    Is there any news on a fix yet?

    @janubande007 - Background Manager does all that you describe as a "solution", and always has. The exception is the introduced bug that does not detect the ready state of WebKit (Chrome/Safari) and Firefox, due to browser caching and a changed behaviour in those browsers.

    A fix has been available in the Github repository (https://github.com/Myatu/Background-Manager-WP), in the development branch. This is where all fixes and developments take place, before they are pushed through to WordPress.org. If you use the development version, always test it first (and I would not recommend deploying it in production, unless you truly need to).
