Build Identifier: 3.5.2.v3557e When there are two overlapping child controls of the same composite, the drop handling events are not as expected. On Linux, the events are not based on which control is visibly "on top", which is the expected behavior (and the behavior on Windows) when a user is dragging something to the drop target. I am attaching a snippet to better illustrate this issue. Reproducible: Always Steps to Reproduce: 1. Launch the attached snippet from the IDE. 2. Drag the control on the left (DragSource) to the controls on the right. The controls on the right consist of a composite (grey/default background) and the composite's 2 child controls, yellow control "DropLabel1" and red control "DropLabel2". 3. Drag between DropLabel1 and DropLabel2 and observe the console print statements. 4. Notice that the dragEnter event does not occur for DropLabel2 when first entering DropLabel2. Instead, it occurs when leaving the bounds for DropLabel1. If DropLabel2's bounds were contained within DropLabel1, DropLabel2 never gets any drop events.
Created attachment 163323 [details] snippet to demonstrate issue Running this on Linux will demonstrate the issue. Running on Windows will demonstrate the expected behavior.
