Ubuntu 15.04 black window border

Question

I just updated to ubuntu 15.04 and all my windows have a black border.

enter image description here

Is there a way to fix this?

Your WM (Windows Manager) does not correctly draw border around your window. What desktop are you using ? which WM ? — solsTiCe, Apr 30 '15 at 19:59
Looks like Unity. Does Unity use Compiz? If yes, try [resetting Compiz](http://askubuntu.com/questions/348438/how-can-i-reset-compiz-settings-to-default). — s3lph, Apr 30 '15 at 21:13

I had a similar problem with the black borders after upgrading to 15.04... i switched from Nvidia 340 to 346 and back and ran the following

dconf reset -f /org/compiz/
setsid unity

You might try just running the latter.

I always have the same problem after resuming from suspend. I've found three different solutions.

~~- Change the appearance theme to something else and back from the command line. Eg. if your current theme is "Ambiance":~~

    gsettings set org.gnome.desktop.interface gtk-theme "Radiance";
    gsettings set org.gnome.desktop.interface gtk-theme "Ambiance";

[edit - the above only fixes currently open windows.]

Run unity --replace from a terminal or the Run Command Prompt (Alt + F2). This will reinitialize Unity, which will take a few seconds, but you shouldn't lose any work.
Install and run CompizConfig Settings Manager (sudo apt-get install compizconfig-settings-manager; ccsm;). Open the settings for "Ubuntu Unity Plugin", click the "Decorations" tab, then check and uncheck "Override Theme Settings". This way requires more work, but doesn't involve your desktop disappearing for a few seconds.
