Even if that function is not bugged, I don't think you should be calling it every single Draw pass. From my understand of the function it is used to toggle on and off the setting, so only needs to be set initially when you want to switch it on (true) or off (false) and not repeatedly set as on in the Draw event every time that event runs (multiple times every step I believe).
If you can't/won't provide code then there will not be much that people will be able to help with. We will always try to help the best we can, but if we don't get given anything to work from (like the correct function name
), then we can't actually provide much more info than just telling you to go post a bug and hope that YYG support does not require code either to help them track down your issue.
But as has now been said, create a bug in the bug tracker and get YYG to confirm it - although you may be hard-pressed to get them to confirm anything if you cannot give them any code either as they will most likely want to see what is happening in the project in case it is something specific to the way things are being done in that project.
I would recommend that you change the title to be correct if it is the wrong function there - this will help other people searching in the future.
