Description of error
While moving my camera along the y-axis, I noticed this bug. I have made a video and uploaded it to youtube, to demonstrate it. Here is the link to it:

Basically when I move my camera along the y axis .. beyond 300m mark, it suddenly jumps to -10000000m or something.. and the screen goes blank. Also, I have not tested it along the X axis or Z axis so far.

This issue was not fixed by the above commit - must be a mixup. I can still reproduce the issue in this bug report. It's not related to gizmos or DOF - this is about translating the camera inside camera view.

Mixed this up with T69140: Can't move Camera Limit widget.

This may be a bug in windows mouse input handling, on Linux (X11) there is a similar bug with mouse coordinates being clamped to a 16bit integer.
