Symptoms

No mouse lock, left/right mouse button actions cause sporadic movement

Reproduction

When the game starts, you can only get mouse control by clicking left/right mouse first. Things work well enough, but when you start the game, you cannot look around until you pause the menu first. After this, using left/right mouse cause sporadic movement instead of the expected action.

Hello @mtdeguzis, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to #79 (comment).

Ok, i'll remember this for the future, hopefully things can get a bit more organized if that's the case or we should be titling the issues with a generic "GAME - APPID - Support issues" Or, create a milestone for each game to track multi-issues.
