inspired by @ panda wine fairy, there is a simple way to solve the problem. Add a v-if instruction to carousel, and the value is bound to the booean value of your control modal. In this way, carousel will delay initialization and achieve the effect of calculating listwidth so that it does not let it fall short of 0

I also encountered this problem, which is caused by a width of 0. As you can see from the source code, the width has been calculated when the page initializes (mounted), this.handleResize (); I extracted this component, and then changed its source code to execute handleResize before calling updatePos. Here are two pictures to understand

you can display the height and width of the picture and related elements or hide the display properties when displaying the page. Compare the display with that after pressing f12
, and then analyze

and F12 are sure it has nothing to do with the slow loading time? Or is the initial value empty for operation assignment?

Building owner, has the problem been solved? I have the same problem.
