> I have a software, a Music Notation Editor,  here that can start in a one-liner and I need to find a bug that only occurs on some systems.

> git clone git://github.com/nilsgey/Laborejo.git && cd Laborejo && ./laborejo-qt.sh
>
> This will download and run my software Laborejo as normal user without installing anything. The only modifications to your system are new dir .laborejo in your home directory and the downloaded files via git. The only dependency is pyqt and git to download it
>
> You will see 5 lines and a symbol. The symbol must be perfectly alingned within the five lines (one pixel above can be tolerated). It should look like this: http://www.wargsang.de/pyqt-bug-report.jpg
> Do you see that symbol shifted up or down or is it correct?
>
> Could you please answer me with the following information attached: Your graphic driver (type ("ati, nvidia, intel" etc. and closed or open source?) and desktop enviroment/window manager (Gnome, KDE, xfce, i3 etc.). If you want to add more information like qt version or X-Server it would be nice as well. Everything display related helps:
> I believe closed nvidia drivers will shift the symbol. I tested it myself on ati and intel graphics, both 32 and 64 bit and it looked good, both on Linux and Windows. Other users with ati and intel GPU's had no problem. But two persons with an nvidia card had the wrong display.
