When I drag any icon on the desktop, the mouse cursor becomes distorted.

Thank you for reporting the issue. Could you explain a bit more details, please? Basically when you drag some items at desktop which is controlled by PCManFM, the icons being dragged should simply move until they are dropped onto something (another place on desktop or some window). Which version of PCManFM do you have, is it at least 1.2.2?

I would also like to add that the symptom of the cursor picking up a "block" of the background image when a an icon is dragged from one place to another does not happen consistently.

I've just upgraded to lubuntu 15.04 vivid.

It is currently using PCManFM 1.2.3

Well, if you look into _create_drag_icon() in the desktop.c file then you can see it creates a drag image starting from cairo_image_surface_create() which is a fully transparent image, then applies clean icons on it, so there is no chance it can pick any bit of desktop image or any random pixels. I'm afraid it might be some cursor rendering issue in GTK+. I have no idea if pcmanfm can do anything on that, and clearly there is no such problem in lubuntu 14.04 with the same pcmanfm 1.2.3, it is installed on many machines in my reach.
