Screenshot demonstrating the problem

When I start to debug using the Android debugger, the graphics in Xamarin Studio start to get distorted when I move my mouse over the Xamarin studio window. After restarting Xamarin Studio, the effect is gone. However as soon as I restart the emulator AFTER I have started Xamarin studio, the distortion effect is back.

I have attached a screenshot to demonstrate the problem.

It's looks like our native graphics surface is getting corrupted. Does this happen with other apps or just Xamarin Studio?
Comment 2 Willem Meints 2013-05-06 02:47:28 UTC
It only happens in Xamarin studio (at least so far).

Could have to do with how we deal with CALayers?  The distortion looks a bit like some initial distortion we saw in the past.  That doesn't mean that the distortions are the "same" though :)

When I launch the Android emulator (from command line) while Xamarin Studio is running, nothing special happens for me.

Additional information is required to debug this issue, I have the following questions:

  1) Does the distortion also occur if the Android emulator is launched from the command line? Or does the distortion only occur if the Android emulator is launched from Xamarin Studio?

 2) Does a graphics-related warning or error show up in the system logs? You can view system log messages using Console.app that is installed by default on Mac OS X.

This should be already fixed. Please reopen if you see the problem again.
