I recently noticed that myself and others using KDE Kwin have had issues with Tomb Raider http://store.steampowered.com/app/203160/Tomb_Raider/

THE ISSUE:
Mouse control locking when trying to pan view to the left, on some occasions this can also happen when panning right. The issue happens after about 90-120degs of movement to the left. Many things were tried to fix this issue, and its persistent.

I contacted Feral about this issue and after a few days got back to me and said its a Kwin problem and I should contact you guys. So I figured I'd just make a forum post.
