Front wheel twist and move in dropouts when braking or on aggressive turns

Question

I discovered that my front wheel moves on the dropouts. I have searched the web to know why? But most of answers was "replace quick release and problem gone" so I replaced the quick-release with different one. Not quite quick-release per se because it is allen bolt(you know hexagon shaped socket) but problem remain. It is quite tight right now I put some strength to tighten it up really good. So I looked at the old quick-release and saw this:

It this quite damaged in my opinion and I'm afraid that because of this my dropouts are damaged too. Could this be the case? How do I resolve this problem? What's to do when problem remain even with new quick-release? Fork is aluminium, wheel size is 29', disc brakes. I would love to provide any information that could help resolve this problem.

A lot of forks do this because the axle path is wrong. It needs to open forward to resist ejection force by disc brakes. The downward path was chosen to do the same for rim brakes. Many companies have made this switch, but not enough.
High-quality internal-cam QRs apply the most clamping force of any type. The simple answer is get any Shimano skewer. A better answer to this question would feature actual cam math, and I would welcome that, but barring that the above is usually a good starting place.
Dropout alignment can be a component of this problem as well. Being an aluminum fork, you'd have to replace the fork to do anything about it though if there was significant misalignment.
