Default Enormous memory leaks in 100.14.19

Well, I will state this problem very simple:

* memory usage with "nv" driver after 1 hour: 22 megabyte
* memory usage with "nvidia" driver after 1 hour: 600 megabyte

Specs:
* nvidia 100.14.19 driver
* linux 2.6.22.8-cfs-v22 kernel
* amd64 platform
* debian unstable up-to-date
* xorg 7.3 / xserver 1.4
* fluxbox windowmanager
* xrestop shows only 3 mb being used by fluxbox, the rest is smaller even

nvidia bug report log attached.

pssst. please generate another nvidia-bug-report.log, this time however
with driver "nvidia" and not "nv"

btw... I have debian unstable on a amd64 too. But I use KDE...

Code:
xrestop - Display: localhost:0
          Monitoring 59 clients. XErrors: 44
          Pixmaps:   13232K total, Other:     144K total, All:   13376K total
(after one hour with "nvidia")

jangeb,
In addition to providing a bug report against the nvidia driver, you'll need to detail how you've determined there is a memory leak.

How there is a memory leak?
With the "nv" driver xorg consumes 22 megabyte of my RAM, while the "nvidia" driver consumes 600 megabyte in the same situation.
I assume that is exactly the definition of a memory leak?
Or should I find it normal that 60% of my RAM is being eaten just to show windows and text on my screen?
New bug report with the nvidia driver is attached.

You should also realise that various applications (best example is Firefox) tend to store graphics in X server's memory. Therefore, the circumstances may differ slightly and the cause of the possible leak be elsewhere.

I used xrestop to inspect exactly who is responsible for the memory use, but it shows no such gigantic amount being used by any external process.
It is used by xorg itself.

jangeb,
According to your bug report, you're using the Composite extension. That extension won't work with the 'nv' X driver, so you're not comparing identical environments.

If you're looking to make an even comparison, you should remove all NVIDIA driver specific options from xorg.conf, and run identical xorg.conf configurations (except for the X driver).

Also, you've not provided your xrestop output for the two different drivers.
