White Background during Frame switching

    i'm nearly done with my Webvisu for the shutters but a strange behavior appeared.
    I'm using Frames to switch the different pages (Light,Shutters,Mainmenue,..)
    When i switch from "Main" to "Light" it is a perfect fast transition.
    But when i switch between the two shutter visu's a very short moment the Background is white.
    Sorry, I can't explain any better.
    Does anyone have a clue what i have done wrong?

    Edit: Now I noticed, if i switch the Visu in the Codesys Runtime it works normal, means no white background for a short time.

    what do you mean with runtime? switch from the visu client in the yprogramming system at the PC or change the variable by IEC code at your plc?

    I mean when i switch between two frames in the Visu. But the short moment of white background happens only when i'm using the Visu in a Browser (no matter which Browser) when i switch between the frames in the Codesys Programm (the Tab with the Visu when im online) it works perfekt.

    Programming System is updated every 200ms only, so probably you can't See the white screen there. Browser normally update faster, depents to the settings of webvisu and tasks. Do you have a big picture as Background, that has to be downloaded from the Webserver, which is different from shutter to shutter? Whats your plc? A Raspberry Pi?

    yes, there is a big background .My PLC is a PFC200 2.nd Generation.Can you take a look at my project? Maybe you are right and i expect to much from the webvisu...

    the reason are the group boxes! After 1hour thinkering i got it. I changed the project to Codesys Control Win and deleted all wago things. After download to the Control Win and opening I got the same effect like you. I placed one groubox at the mainmenue and the white background appears there too! So the PFC ins't the problem!
    Send the project to codesys support --> Meine Frage

    thanks for sending the project via 'my question' for me it looks like enable
    'Support client animation and overlay of native elements' in the visumanager will solve it.

    once more a little unimpressive checkbox with unsuspected effects 😎 now it works..
    Thank you Edwin 👍

      That checkbox is doing way more then just being unimpressive with a unsuspected effect ;)
      The checkbox changes the way all visualization elements are drawn in the client from a global drawing context to a drawing context per element.

        is it possible for you or the promotion people to make youtube videos, explaining how the visualization is working in the background and how you as experts use it? That will be great! And I haven't seen a offer for a training about creating good visualizations with Codesys?

          As far as I know there are currently some visu trainings in the making.

          Never let a developer design a website. Mine always look ugly ;)
