I work on a dual monitor setup with the output undocked and put on my second screen. When moving a docked window component from one window to the other by drag-and-drop on the component tab i get a black box with an icon of the component in the top left. Sometimes this black box stays visible even after the component has be re-docked in the other window and does not dissapear until Neteans is restarted. I will try to attach a screenshot later.
Created attachment 53972 [details] Image of screen artifact
Reassigning to core/window system for evaluation.
i suggest closing as wontfix as the window dnd has been rewritten
As Standa said, please try latest development build, DnD should be fixed here. If error still appears, please reopen with comments, thank you.
