Cant click collision preset 'OverlapAll' bug

Bit of a strange problem… the menu for ‘collision preset’ moves when i click it and i cant select the option ‘OverlapAll’ so that foliage is not painted onto mesh. the mouse seems to ignore selected drop down menu and flicks about. Anyone have a reason for this would be great to hear. dont know if this is a known bug. Many thanks

Funky. Are you using screen scaling in Windows?

what exactly is that? and where can i view it in settings? i am using windows 10 computer

yes i have 100% enabled. weird, just now when i opened another app but still had unreal on another screen the dropdown menu behaves normally, but when having just unreal open, doesnt work, interesting

You could try resetting the layout but I doubt it’d help much:

Apart from that, are you running a unique resolution? There are some laptops with weird aspect ratio, for example. Any software that creates screen overlays?

I have ‘fix scaling for apps’ enabled. I can enter custom scling 100%-500%

That ^^ should be probably at 100%, as should this:

I’ve seen folks complain UE4 menus misbehave with scaling applied. Not sure if you’re affected.
