Amen!
JFTR my stone age ATI graphics, when using the FLOSS driver, can be
used without any performance issues for Google Earth, it's quick as
a flash, but using Cinnamon is impossible. That's ridiculous!
Cinnamon and similar desktops are simply written by people who
don't know how to program correctly. It's not a driver acceleration
issue, if it's possible to use software such as Google Earth
without performance issues, but using a DE as Cinnamon is
impossible.
Seems like you are right, no problem/Xrun with Kernel: 3.19.0-rc5
x86_64 when I use LXDE instead of Cinnamon.
So it seems that, as soon acceleration in the nouveau driver becomes
improved, Cinnamon isn't suitable for Audio work anymore.
You should run Google Earth on LXDE. Likely the acceleration for your
graphics provided by nouveau is perfect for such advanced 3D software.
Keep in mind that Google Earth allows quick moves from space to street
views, it not only does stress the 3D acceleration, but at the same time
it does stress the Internet connection.
As soon as a desktop environment/window manager needs more resources
for opening or closing a window, than Google Earth does need to move
from space to a street, IMO the DE/WM is broken.
Didn't know what the cause is, but CPU usage of Cinnamon never goes
above 10% , even if I stress a lot with window moving pop-up/down, etc.
Also MEM usage is with more then 700MB (firefox, evolution, geany, etc.
opened) moderate.
With kernel 3.4.xxx-rt there are no problems/Xruns at all.
Broken or not, I'm not as fast as you, to diss a Application/DE or what
ever. Sure there is something wrong in Cinnamon, but, I'm sure that it
could solved, as soon one find out what it is.
Otherwise, Cinnamon is a nice looking Desktop, with nice effects and 3D
impression on the screen.
For now I know, that if I need to switch to never kernels, I've to
switch back to LXDE or a similar lightweight desktop.
