If your environment is set up to point locally and you try to preview or run the test case using same environment then you will get below error message.
If you press OK in above dialog box then, you get infinite mirror screen as shown below which makes watching preview almost impossible.
How to fix it:
While designing and previewing test cases, instead of using the “local” environment try using display “Local (Display 1)”. It will automatically minimize Studio and during image capturing and while running test it will not create infinite mirrors.
