G3-572 camera glitches

I rarely have to use the camera, so maybe this is why I didn't noticed this issue before.

After few minutes of camera usage, or after some change of brightness, or a fast movement in front of it, the camera image stutters, sometimes it presents noise lines, really strange stuff. I was thinking about some faulty connector, but it doesn't seem to be affected by any lid position or vibration to the device, more to the high-speed movements the camera would have to process.

Someone here faced some problems alike?
