Public bug reported: Hello friends. I stumbled across a graphical issue that I wanted to report. I was able to duplicate this on Ubuntu 14.04.3 LTS as well as Ubuntu 15.04 with all of the updates done on both systems as of today. Both systems also vary quite a bit in hardware (l14.04.3 system = Latitude 7440 laptop with Intel graphics, 15.04 system = desktop with Intel CPU and Nvidia 9600GT/Nouveau drivers).
I created a screencast of the issue happening. Please note this screencast is of my 2nd monitor only. To reproduce (which can sometimes be a little inconsistent, though a matter of 60 seconds I was able to replicate it -- then once it happens it seems hard to ignore), have a couple windows on each monitor. In my case, I felt as though I noticed the issue more frequently with Firefox, though I did replicate it with Libre Office as well. Click on the 2nd display to activate it as the active monitor. Move the cursor to the 1st monitor, but do not click anywhere. Press the super key to activate the dash. That's it. The dash seems to follow the cursor and open on the monitor the cursor resides in, regardless of where you last clicked. With the second monitor "active" (via a prior click) but the dash opening on the first monitor via keyboard shortcut, it seems to instigate the issue. Pending that you have a few windows open, it won't take long to replicate what you see in the video. In the video, all I did on the 1st display (what's not seen) is move the cursor to that monitor and press the super key. https://www.dropbox.com/s/vr0k0qp1l01bxz4/Ubuntu-Flashing-2nd- Screen.mp4?dl=0 Thank you for your hard work, time, and energy!
