Blank delayed starting within tabs

@ayek we looked into it and its a strange behaviour. we guess it is related to theme / other plugin’s css/js. Can you please try deactivating all other plugins and see if the error persists. then enable one by one.

Hi @eedee
Sorry, seems I didn’t get notification of your reply.
I’ve tried with all plugins deactivated, beside Tabby Responsive Tabs – the same behavior :/
Pro version of Gutenslider makes no difference.
Can’t you figure out why this happens?

Can you please try setting the slider to a fixed height and see if that works? If yes, you could set the heights accordingly for every breakpoint.

Probably the tabs content is inserted with js / images are loaded lazily and gutenslider does not know their height before it goes to the next slide. Are you familiar with javascript? Because then you could call update methods on the slider after switching a tab.

No success for fixed height nor in pixels, neither for percentage ones.

Tabs content is not inserted with JS, just arranged with CSS.

No difference if we disable WP default lazy loading feature
add_filter( 'wp_lazy_loading_enabled', '__return_false' );

Do I need to seek another solution for slider inside tabs?

I will have a look later this day and get back to you @ayek

We tested a local install and could not fix the problem with tabby sorry. However we see the plugin is not tested with latest wordpress and adds content with javascript. there could be workarounds somehow but we did not find them. sorry
