I suggest you swap the skewers to see what difference they make.
Incidentally, Sheldon Brown and many others whose judgement I respect consider external cam QR skewers to be a bad design. I have had them come loose on two occasions, and will now only use internal cam skewers, which largely means Shimano because they are now almost the only internal cam QR available.

It might be worth turning the bike upside down and resting it on the saddle and bars, then open the skewer and see if the wheel stays aligned in the plane of the frame, and whether it remains so when the quick release is tightened and loosened again.
I'm sure I've read of at least one case where the surfaces of the drop outs which rest on the upper surface of the axle were not properly aligned, with the result that the axle on one side was not in contact with the drop out at the 12 o'clock position, but rather at the 11 o'clock or 1 o'clock positions. Under significant pedalling load the misalignment resulted in movement of the axle despite the clamping force of the QR. I suspect such misalignment might not be easy to detect, but it might become apparent if you try holding the tyre lightly close to the bottom bracket and wiggling the wheel slightly from side to side.
