I just installed Kubuntu 15.04 and I'm facing a weird mouse issue. Sometimes when I try to drag and drop a file/window or select some text my mouse looses control, (e.g. if I try to move a window it will move a little then loose focus, if I try to select some text at some point it will get deselected). It's like I would release the mouse button.
I want to mention that this is NOT a hardware problem, the mouse works perfectly fine on Windows or other distros, even on other flavors of Ubuntu 15.04.
I've been searching for a fix for hours, and can't make it work, any advice would be greatly appreciated!
