Test Case

If you run the following test case on an ipad2. When you rotate the device to landscape you run at 1/3 the speed.  This only happens on the ipad2.
Comment 1 Chris Toshok 2011-08-08 18:56:03 UTC
strange.  I can definitely reproduce it here, but at least once it hasn't happened on rotation.

let me dig a little.
Comment 2 Chris Toshok 2011-08-08 19:14:30 UTC
even stranger..  I added some debugging CWL's and now it's fine more often than not.  Have you tried setting AutoRotate=true; in your EAGLView ctor?
Comment 3 James Clancey 2011-08-10 02:06:20 UTC
I tried AutoResize = true; Still causing major lag on the ipad2 version.
Comment 4 James Clancey 2011-08-25 20:57:41 UTC
Any update?
Comment 5 Chris Toshok 2011-12-15 23:35:10 UTC
resetting this to the default assigned-to..

This bug was targeted for a past milestone, moving to the next non-hotfix active milestone.

Moving the target milestone to "far future".

updated test case

For the record attaching my updated test project (the original doesn't compile anymore, due to csproj changes).
