it also happens with the latest commit from the master and i think it happens because the first item (or selected one ) in the drop down list is empty with Transparent background to show what's behind it in the combobox

that why you only notice it when it have a different element with a different color behind it like your desktop background etc when it expand out of your app border or on another controller

sorry but i have to say it
it's a feature not a bug

@AmRo045 thank you for the repo project.
I am not able to reproduce your exact issue but there is some issues here that should be addressed.

Reproduction steps (works on latest demo app as well)

1. Set FlowDirection="RightToLeft" on the window.
2. Set FlowDirection="LeftToRight" on the ComboBox

Observed: The selected item disappears from view when the ComboBox's popup is open.

After a little digging it appears the issues is with the ComboBoxPopup.VisiblePlacementWidth getting set to 0. It appears that the hit testing being down is making some assumptions about the flow direction and needs to be updated to properly handle this case.

unfortunately this problem just occurred to me in the latest version and the fix you provided in your last comment did not work for me at all :'(
