Created attachment 501651 [details] white boxes remaining behind after glines moves Description of problem: Five Or More leaves box-outlines behind after a move. Version-Release number of selected component (if applicable): 3.0.1.1 How reproducible: Easily reproduced. It happens 100% of the time. Steps to Reproduce: 1. Start a new game. 2. Click a ball with the mouse. 3. Click on an empty destination square with the mouse. Actual results: The ball moves to the destination square, and a white box appears around the destination square. Expected results: The ball moves to the destination square. The white box shouldn't be shown at all. In previous versions the white box was used only when keyboard arrow-keys+enter were used. Additional info: The board gets redrawn when a line is completed, so some of the white boxes go away. I have fast moves turned on, and a non-standard background colour set in preferences. I have attached a video of the bug in action.
Created attachment 513525 [details] only show white box outlines when we're supposed to show them
The white boxes that can sometimes outline a square get enabled when the arrow keys are used, and they go away when the mouse is used to click a ball. The preceding patch fixes the problem of many white boxes hanging around. It also fixes the problem of white boxes showing up when I click on a ball. I haven't done the bug-research to find out why the white boxes suddenly showed up when using a mouse, so fixing this may cause a regression for somebody else. Please commit this patch.
