Created attachment 354935 [details] Screenshot of the partly off screen tooltip. The top end of the screenshot is where my screen ends. While experimenting with multi-line tooltips we discovered that the algorithm to choose where to render them likes to place part of them off screen, by preferring to have the end of the tooltip always start at the mouse location. This can be seen in the attached screenshot. (What you see there is part of a screenshot. I have cut off something at the left, bottom and right, but the top is just where my screen ends) Now I understand that we are maybe overusing the tooltips here, but still it would be nice if the Tooltips where _not_ rendered partly off screen if possible.
