This most likely is a driver issue, not a cheese issue. cheese does some things which can stress certain drivers. Given that qc-usb is not provided by Fedora this is a not supported solution, so I'm going to close this.

Note that work is underway upstream though (and I'm participating in this work) to get qc-usb ported to v4l2 and merged into the mainline kernel, A very preliminary version of this work is available here:

But at this early point in its development I cannot advice you to test it. When I find the time to work on this I'll make sure to also test it with cheese :)
