Hello Opamp77,
After looking into your steps to reproduce this issue on our end, I was unable to do so. I have a few questions for you that will help narrow down what issue it is that you are experiencing. \
Quick questions:
- Can you reproduce this issue in a clean project?
- If so, could you provide any steps that may have been left out of your original post?
- Could you provide your dxdiag?
- Could you try closing all other editor windows and tabs other than the main window for the editor that is being used before running the test?
