Comment 31 for bug 881526

Because this normally happens after first boot, but not in posterior ones, I greatly suspect this is a hardware bug.

Probably this is happening because of the GPU passing from a cold state to a warm state too fast, under graphic demanding operations as watching videos are.

And Windows users won't be experiencing this as the GPU doesn't stay in a maximum power state all the time.

So this should be a bug in the Linux kernel, Direct Rendering Manager's, Dinamic Power Management feature.
