I can confirm, but with another plugin. This happens to me with the third party plugin "File Reader". Simply place one on the layout and preview and the button shakes. It's probably happening universally to text-related stuff perhaps.
EDIT: It seems to only happen when it scales or if I zoom in with ctrl+mousewheel. When the application is at it's normal zoom level and not scaled, it does not vibrate.Jase002013-01-14 06:03:46
