Why did you install the 32-bit version? You have a 64-bit system,
right?
A few months ago, I installed Jessie 32-bit LXDE desktop in VirtualBox
on a 64-bit host (Wheezy 64-bit) to test video streaming from different
sources. Videos ran awful like what you describe. I reinstalled, but
the 64-bit version. Videos streamed perfectly. Everything else
remained the same. I just let the installer do its thing.
Why GNOME3? Could be it's the problem. I've never been able to try it
on my systems. It won't run. My plain vanilla graphics cards just
don't have support for it. I get the "fallback" desktop. Also, GNOME3
has become a bloated resource hog, IMHO.
So, first try the 64-bit version with GANOME3, and if that doesn't
solve the problem look to a lightweight desktop like LXDE or XFCE, or
just a window manager.
And, of course, check you've got the latest video driver installed.
