You have been subscribed to a public bug: Whenever I open any new window, a black border around the window appears for a fraction of a second (like a flicker).
Although this doesn't happen very frequently, happens around 3-4 times out of 10. This is most noticeable when I right click on Desktop and click on "Open terminal". I can replicate this bug every time when I open terminal this way. Also, when I open terminal by pressing Control+Alt+T, the caption buttons kind of grey out after the flicker and are un-clickable. They look as if the window is not at focus. Workaround is to switch to another window (Alt+Tab) and then switch back to terminal.
