Bug 320472

When I copy a large (video) file from my NAS to my laptop and the "file transfers & jobs" notification appear, I notice that my laptop is rapidly getting warmer. Using powertop I discovered the reason for the laptop getting warmer is almost 100% gpu usage. I don't think such a small animation should stress the gpu that much.

Reproducible: Always

Steps to Reproduce:
1. Copy a large file to your machine
2. The notification window should appear
3. Check gpu usage using powertop
4. Check again after the copying has finished
Actual Results:  
Powertop reports "Powered On 96.5%" or a similar value during the copying process

Expected Results:  
In my view, the copying of a file to the laptop shouldn't cause this much stress on the cpu

Not sure if this is related, but I see the following entries in ~/.xsession-errors when I start a transfer:
