Comment 4 for bug 893925

Which graphics card you use, which driver do you use?

When reporting a unity bug it is really helpful to report it using the command 'ubuntu-bug unity' so that the bug report have alot of useful logs about your system... Can you run 'apport-collect 893925' in a terminal so that we have a little information about your system, Moreover I believe a video to show the problem would also be really helpful. Thanks!
