I'm running Ubuntu 13.04, and the problem is that sometimes the mouse pointer icon is stuck with the busy cursor (I can move it) or spinning wait. When this happens, if mouse cursor is on any window titles, The Unity Launcher and Panel, the cursor becomes busy. After a while, the problem simply goes.
I can't send a screenshot because it doesn't show up in the screenshot.
I face this problem when try to run some applications:
- Ubuntu one
- gksudo nautilus
- Seagate Barracude 3.5" 7200RPM HDD
- MSI Z77A-G43
- Kingston HyperX 1600MHz DDR3 RAM 4GB
- Core i5-2500k
- My computer uses the Intel HD 3000 that is on i5-2500k
I don't use any other driver than the one that comes with Ubuntu 13.04
Here is a video that you can see the problem produced: https://www.dropbox.com/s/61rzeutdogog821/out-2.ogv
I can say that there is not considerable change regarding the consumption of system resources while the cursor is spinning.
