Fedora/Gnome3 : Display Problem on my hardware.

[Madhurjya Roy]

Thank you for the response!

As a high school student, I'm no expert in the department but
shouldn't it be actually a GNOME3 shell bug, considering the fact that
the same driver worked when used with other DEs?

And if indeed, it's a driver problem, then the problem should lie
within AMD's main codebase. That'd explain the fact that even the
proprietary drivers couldn't resolve the issue.

I'm also wondering if the problem is in anyway associated with some
AMD CPUs in general! One of my friends, also noticed some occasional
minor distortions on his Debian (GNOME) system running an AMD Athlon
x64 4600+ processor with an old nVidia nForce integrated GPU.

Cheers,
Madhurjya Roy
