I have been experiencing a strange graphical bug which I'd like to report on Launchpad.
The bug occurs randomly when pressing mouse buttons in some applications, like for example when I resize tables in Libreoffice Writer or when I use autoscroll in Firefox. When a mouse button is pressed, a black screen is displayed or sometimes the login...The bug is transient: it disappears as soon as the mouse button is released!
I'm basically facing 3 problems before I can report it:
- I don't know how to reproduce it
- I don't know which package is faulty (hardware driver?xorg?unity?, etc)
- I don't know how to show evidence of it! A screenshot cannot capture it...
This is really annoying and I would really like to report this bug so it can be solved.
Please help me!
