Well, I think that we can rule out the proprietary Spotify client, as I haven't been able to use it recently because of a missing (deprecated) dependency. My current 15.04 installation is fairly new, as I returned to 14.04.2 for a while, but decided again to use the newest development version. I have to say that I don't see this bug that much often as I used to, I only came across it once throughout two weeks of everyday usage. I only had free software running then, available in the main repositories, namely Firefox, Nautilus, Terminal, qBittorrent. I started to close windows in this order: qBittorrent, Nautilus, Firefox. After closing Firefox, the performance was normal again. Note that I left the terminal window open.
I am using the recommended proprietary Nvidia drivers, and I am affected by an another bug (having thick black borders around GUI elements), which occurs after a sleep/resume cycle. I will do some experiments to find out whether this bug is also connected to suspending the system. That's all for now. I would like to offer some of my free time for further investigation, I will just need some tips on how to proceed. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

To be more precise, when my system happens to be in this state, every animation, like moving windows, opening menus (fading in/out), or opening the dash is very choppy (I would guess 5 FPS, but I didn't perform proper measurements). I could not find the triggering element, although I know that closing some windows will solve the problem, after which I can reopen those windows, and have normal frame rates. In Compiz Config Settings Manager, I already set the refresh rate to the correct value of 60, and disabled refresh rate detection. I believe that from the attached data it's clear that I'm using the latest nvidia drivers provided by Ubuntu.
