It also happens when placing water buckets and magma buckets (rapidly placing down and then picking it back up).
I don't have a second mouse to test hardware right now. (but My mouse doesn't seem to have issues otherwise)

-placing two blocks instead of one, occasionally (I was placing with some regularity, that should make it clearer)
-shield stuttering movement. (first try at the very beginning)
-melon slices stuttering the eat function. (third try)
The problem wasn't as pronounced as it was when I put the report up, but it's still enough to be a problem.
After some investigation, the mouse is the problem. Sorry!
