[Regression] Drag and drop elements from palettes with cursor not convenient
In musescore 2.0, when dragging an item from the palettes, there's this line showing you where it's going to be placed (see musescore2screenshot.png below), but in the master version, it's not there. Plus, in 2.0, the cursor is a normal arrow, but in 3.0, if your cursor is not pointing at a valid place, it's a red circle, which makes it hard to know what you are actually pointing to.
Both things combined make it quite hard to drag and drop items.
Try it: in 3.0, create an empty score and try to drag and drop a fretboard diagram to anything small (a whole rest for example).
P.S.: Sorry for the quality of the image below, it looks like the rendering problem is now solved in 3.0.
