zunath commented 2 years ago

To Reproduce

Click on the chest
Scroll the UI window down to the bottom
Click the "Update List" button
A vector error will display

OS Windows
8193.34

No content overrides
Regression from 8193.33 -> 8193.34. Downgrading to .33 fixes the issue

If needed, describe the bug

I believe this is an error with the way NUI resizes the element after its contents change. It's consistently reproduceable any time you have a bound list, scroll to the bottom of said list, and then update the bound list with a smaller set of items. If it helps, this issue was not present on 8193.33 and downgrading addresses the problem.

This started happening quite frequently with NUIs that worked without issue previously in version .34 and it is very annoying.

Daz has produced a workaround for the issue.

skill_window.nss: l96-97

mod_nui.nss: l84-87

Another workaround is to ensure your list size never reduces and instead make all items within the list are set to Visible = False.
