Scroll bar resizes / changes speed


I noticed that the scroll bar of the e.g. Details panel of the Editor resizes when it is moved. Sometimes it even starts to flicker for one frame ( showing a very long scroll bar ).

This looks and feels very weird when I drag & move the scroll bar with the mouse because the moved content of the panel seems to move very inconsistent at different speeds, though I move the scroll bar at the same speed. The scroll speed seems to be consistent when I use the mouse wheel.


Hi UE XenoEgger,

Thank you for submitting a bug report. I have reproduced the issue and logged it as UE-40387 which you can track on the following link: Unreal Engine Issues. Please be aware that since the issue must be reviewed and prioritized by our development staff, it may be a while before it can be addressed.


Why won’t you fix this ?

This flabby behavior is really annoying and makes the scroll bar control very inaccurate!

I’ve updated the following post to include the Developer’s notes as to why this will not be fixed: UE-40387
