Listbox resizing performance

General
1

Hi,

i have a pagepanel with multiple pages. i place a container with a listbox on every page, the listboxes are filled with some database-records at appstart.

When the app starts, the first page with the filled listbox is displayed. In this first listbox, there are more records than the actual window-dimensions can display. So when i then resize the window, the resizing is not very smooth.

When i change to the second page with a listbox only containing a few records, i can resize the windows and all resizing is very smooth.

When i then go back to the first page (with lots of records in the listbox) i can resize the window and now it does it very smooth as well.

Are there any know issues about that?

Are you on Mac?
If so, try to disable the focusring on listboxes.
There is a bug which really slowdown listboxes with focusring.
