It appears after i take any screenshot and remains for 2 seconds approx. and its quite irritating as screen becomes type of unresponsive until it disappears.
Any help will be appreciated.Thank You.
Don't think you can.
If you go into Screenshots apps system settings and turn off "Display over other apps" the screenshot app stops working.
When you try to take a screenshot. It will just display the message for wanting the permission to display over other apps and won't actually take screenshots.
I suppose that's the UI behavior and the same cannot be disabled.
