so you downloaded (and are reporting about) the upstream version of
MegaGlest, not the Debian package? If this is so, please report any
upstream MegaGlest bugs at http://bugs.megaglest.org (one-time
registration is required).

For a more detailed list of information that is useful in determining
what the problem is, please have a look at this (upstream) forum post
which is dedicated to the topic of effective bug reporting:

When you say you "experienced the same result" of the screen "[playing]
crazy" testing with Gnome 3 on Fedora 15 and on Debian Wheezy, are you
saying that this happened after using MegaGlest 3.6.0.3 on both
platforms? I.e. were you really running MegaGlest 3.6.0.3 on Fedora 15?
Or a different version of MegaGlest, or yet another application which
triggered the same or similar behaviour?

I'll try to sum up the information you have provided so far, please
verify it is correct or provide corrections as needed:

* You are experiencing an issue on your Debian Wheezy installation on
your current laptop which you describe as the "screen [playing] crazy"
as soon as you exit MegaGlest.

* You state that this issue occurs with Gnome 3 but not with XFCE 4 and
Gnome 2.

* You state that this (or a similar) issue affected your earlier Fedora
Core 15 installation (also running Gnome 3) on a different laptop.

* It is unclear whether this behavior is only triggered by MegaGlest or
can be triggered by other OpenGL based applications, too.

* It is unclear which, if any, versions of MegaGlest was triggering this
behavior on Fedora Core 15, and whether that was a Fedora package or an
upstream installer.

* It is unclear which hardware your current laptop (running Debian
Wheezy) and your earlier laptop (running Fedora Core 15) are/were using.



A better description of "the screen [..] plays crazy" may be helpful.

Surely more information on the (mostly video) hardware on both systems
can be of interest here, as well as taking a look at ~/.xsession-errors*
and /var/log/Xorg* at the time when the screen started to "[play] crazy".

Please also read http://www.debian.org/Bugs/Reporting - especially the
section titled "The body of the report".

Most likely the issue you are reporting is one of the following:
* A bug in a compositing window manager such as Mutter/Compiz
* A bug in your video drivers
* A hardware or firmware issue (video or memory are most likely candidates)

Based on the (few) additional details you have provided this issue is
probably not caused by the "megaglest" package in Debian GNU/Linux
Wheezy. Please try to reproduce this issue using other complex OpenGL
applications to confirm. If you can, please reassign your bug to the
proper package as explained at
http://www.debian.org/Bugs/Developer#requestserv
If you cannot reproduce this issue with any other OpenGL software, are
convinced it is a Megaglest bug, but are actually reporting an issue
with the upstream version of MegaGlest, please report this issue
upstream instead and close this bug report (or ask for it to be closed)
'unreproducible':
