Hello Sorry so late,
I had this same problem, unfortunately you have to have the cursor enabled. but I found a little trick.
Create a blank image in gimp or paint shop pro. If your dont have either find a blank icon in google image search. And click one preview tile at the bottom and and hit control+A to highlight all tiles then click to highlight the the cursor option in the properties box. DON'T UN-check the tick box. Then below you will see the pointer properties option appear. Click it. Then click the "import from" button. And choose your invisible icon. Select it, click ok, and all your pointers will show as a squared jagged box. Which you will see in wink, but once you click the render green arrow, will produce your demonstration mouse pointer-less. Yay!
