Motivation / Problem

Fast forward behavior is erratic when using OpenGL and vsync is enabled. (it mainly doesn't work, but every few seconds it jumps working for fraction of second).

Quick ping to @michicc , if there aren't potential problems by taking the video lock before the game-state lock? I remember something about screenshots, but I am fuzzy on the details.

I don't think this PR changes anything in that matter. Screenshot locking is broken anyway. (it can blow up when triggering screenshot via rcon)
