Post Bug Report

Update:

I installed, latest nvidia(beta) 295.09 in this Debian testing system upgrading from 290.10 . but, the poor slow performance/rendering issue is still persisting.

I have attached nvidia-bug-report.

I tried to verify that the problem is with mutter window manager and nvidia driver interaction.

steps to reproduce:

* login into Gnome Classic(fallback) 3.2
* run "mutter --replace" (I've installed mutter 3.2 already)
* try using browsers,image viewers all pages/images looks garbled,misaligned especially if You slowly scroll with mouse. if I try to press any key or launch any application meantime like for example gnome-screenshot tool, the page suddenly align correctly. same with image viewing tools also. I believe, after using for few hours, the image acceleration became slower.

However, with metacity window manager, there is no such issues. gnome-shell has libmutter0 as dependency.
helpful people at Debian forums suggested the image rendering issue may be related to Clutter Library as "eye of gnome/shotwell" like apps render images out of sync.
Here are the details of installed versions:
