Hi,
Actually i find a solution by solving an other problem.
My other problem is the slider height was not always the good height depending if the menu is absolute or not. With absolute menu with slider under the menu, the slider need to be fullscreen height. But on mobile, menu is not absolute and the hearder is 90px height. So slider height need to be 100vh - 90px height.
The way i found to do that is to add (see picture) .uk-sticky-placeholder in the offset container. Like uksticky is 0px height on large screeen and 90px on mobile, slider height is always good.
To my surprise, il also solve the problem i mention earlier.
But problem seems to still exist.
Here a video :

Slider 5.0.17 have the problem :

Slider 5.0.17 with .uk-sticky-placeholder in the offset container have no problem :

Slider 5.0.14 without .uk-sticky-placeholder have no problem :

Seem like the 5.0.17 does not dynamically write the slider height parameter when user change windows screen. For a reason i ignore, looks like when put something in the offset it does it again.
So for me now no problem but maybe it will be usefull to another people.
I wrote to unite slider to explain tham.
Thanks
See you
