Been seeing this for a while now, finally got around to grabbing a video of it. What I'm seeing is that if there is a portion of the model underneath the cube in the upper right, sometimes it will select something as I release the left mouse button. Sometimes its one face, sometimes a whole body, sometimes its the entire project. Very disconcerting!
In the attached video, I made a simple model, just a box and a cylinder - what it is makes zero difference. I zoom in to get it to more than fill the screen, then start left-click/dragging on the cube to turn the view around. A couple of moves in, it selects a face for no reason. I THINK it does this more if the mouse is still moving as I release the button, but not sure if that matters.
I've had this happen when using a tool dialog, and turn the model to see/select more features, but it sometimes ends up slecting other things because of this bug, and I have to deselect/start over again. Complete waste of time when this happens.
