Screen recording with mouse pointer in the wrong place

I'm so glad to have found this article as I was almost ready to cry yesterday when I could not work out why my screen recordings in Replay were suddenly so grainy and poor quality compared with my previous attempts. I even tried re-recording my screen in Storyline then publishing and importing the MP4 file into Replay to see if this would fix the issue - but to no avail! I haven't been using Replay for long and hadn't changed my screen resolution recently to the best of my knowledge, but after re-recording this morning it does seem to have fixed my issue - thank you!
