It's not a big bug and I think I already mentioned it on the steam forums a while ago with with release approaching I am wondering if you could take another look at this issue.
While not being a big thing, I think it leaves a taste of "unprofessionalism" which is unnecessary.
As the topic name suggests the scrolling combat text currently interferes with the curor. Meaning that the cursor changes it's form when combat text is under it. I also guess clicking doesnt work at that point but I didn't test that.
I made a little demonstration and uploaded it here: https://www.youtube.com/watch?v=_NZQUK4T0lU
The black border you see around the cursor only shows when recorded via DXTory. When recorded with FRAPS no cursor is visible at all.
