I'm having trouble finding an answer to this, as all my searches come up with people suggesting ways to make a camera shudder effect!

My problem is that in Blender Game mode, when I switch to camera view and play the game, the background outside of the camera view jitters/ flickers very fast.

If I start the game in user/ortho view, it doesn't happen, and when I move to the next level, the camera view is perfect. It's only when I start the game in camera view.

Does anyone have any suggestions? Is this a known problem?


  • $\begingroup$ This sounds strange. Does that always happen (with any file)? If not can you post a demo file? $\endgroup$ – Monster Sep 26 '17 at 7:33
  • $\begingroup$ Thanks for your reply. Yes, it happens with any file. Here is a link to a screen grab showing the problem. In User view it doesn't happen if I hit P. In camera view it happens if I hit P and when I hit embedded player button. The player button also goes crazy in both views. See for yourself here: link $\endgroup$ – RexTheRunt Sep 26 '17 at 12:51
  • $\begingroup$ By the way, I meant to include this information: I'm on version 2.79 on Mac OS 10.12.6. Also just tested again and it does keep on happening on subsequent levels. $\endgroup$ – RexTheRunt Sep 26 '17 at 13:02

This seems to be a mac issue - the solution is to change the Window Draw Method in User Preferences/System - from no multisample to Multisample 2 at least. multisample setting
