Detailed Description:
-----------------------------
I have observed multiple issues with rendering under the DnD client - I combined them all into this one bug.

Issue 1: When a flower is dropped it "flashes" for a brief moment only when mouse is stopped, if mouse cursor is in movement the flower won't flash

Issue 2: When a flower is clicked it moves a couple pixels - even if the mouse hasn't moved.

Issue 3: When you release the mouse button after draging and dropping, but don't move the mouse the incorrect cursor is displayed.

Issue 4: When DND client is spun around it's axis and a flower is picked up to be dragged it "snaps" back to it's original position - sometimes off the mouse cursor

Steps to Reproduce:
----------------------------
1. start weston under X11 or DRM mode
2. ./dnd
3. Drag and drop items (same window is OK), click items, spin window and drop items, release mouse and observe the incorrect cursor

These are... great.

I've just mailed off a patch that potentially resolves #3

I can't reproduce #2.  Perhaps this has been fixed in some way, or perhaps it's just really difficult to let go of the mouse button without moving at least one pixel?

I guess #1 occurs because the item is actually not present for a screen refresh between mouse button release and addition to the dnd client window.  I'm not sure I can think of a way to resolve this.

#4 is simply because the dragged item loses its orientation when it leaves the rotated window.  Very gross.  I'll see if I can come up with something.
