I'm having a problem right now with my window frames' opacity settings. For some reason the active window very often (but not always) has a half-transparent title bar. This is really distracting but so far I haven't found any way of getting rid of this effect.
I think the problem might be caused by settings I made using the "Ubuntu Tweak" tool. But whenever I try to reset the window frame settings in "Ubuntu Tweak" the application crashes. I already tried reinstalling it but the problem still remains.
Additionally the hover effects (on the max, min, and close button) are not working properly.
Do you know how to reset the window frames' opacity settings so that active window frames have no transparency at all?
Thank you for you help!
