This morning I updated a project I am currently working on that is using the Material theme to the newest Winforms controls release. Before when I would click on a button, the button would do a little "click" visual effect and then that was it. Now when I click on a button it plays that effect and then the button turns purple. Was this theme changed and how do I fix this? Having a button turn purple is extremely distracting and will most likely confuse the users of my programs.
