    • Hello,

      Thank you for providing this information about the issue. After thorough testing, we are unable to reproduce this problem in Edge. Please update this case if you have new information for us to consider, and additionally run dxdiag (Windows key + r and type dxdiag, enter, then click Save all Information) and attach the txt file.

    • Hello,

      Thank you for the continued assistance. Please update to the latest Insider Preview (currently 16226) and open a command prompt and run dispdiag when the problem is happening. Reopen this case and attach the .dat file so we can see what is happening with the display stack.
