Hi @ruanpepe , for what I have experimented, the iFrame mode has lots of bad visual effects and they are inherited from the underlying AdminLTE package, when they show a page embedded in the iFrame mode, the sidebar for example is removed using Javascript, but there is a transition animation that don't make it look smooth. Also, the AdminLTE package appears to be currently unmaintained , so I think we can't expect any improvements on how the i Frame mode works and we can't do much on this package to solve those issues.

Now, in relation to your problem, are you sure it's exclusively related to preloader on cwrapper mode, i.e, have you tested the same with the preloader disabled?

Also, as a workaround, you may try to increase the value in the loading_screen option of the iframe section (for example, to 2000). That way, maybe the loading screen may hide those bad visual effects that happen while loading the tab.

Hi @dfsmania. How are you?

Yes. The iFrame mode is very useful, but it comes with some visual issues.

I tried now without preloader, and the behavior is still going bad. Then, i've been using the preloader with fullscreen mode and it was "hiding" the menu bug. I'll keep the preloader in fullscreen mode.

Thanks for your time.
