Solving this problem if you have AMD ReLive.
In "Radeon settings":
You need to go to Gaming > Global Settings > Performance Monitoring > Toggle Performance Logging Hotkey
You will see this is bound to Ctrl + Shift + L (so the shortcut is used - just buried).
To remove the shortcut (not an obvious process at all!) you need to click the Toggle Performance Logging Hotkey button, it will then ask to enter your hotkey, you then press delete - that is Del (not backspace, not esc or anything else - the Del key).
Enjoy and don't lose two hours like me =(
