I have had this mouse cursor problem for quite some time in HoN and after some time I decided to finally try and fix the problem. I have a HD 5800 graphics card and have seen a lot of other threads with the same graphics glitch.
Suggestions are to update graphics drivers. The other night I tried the latest driver and after 1 game I had to roll back because of this stuttering scrolling bug in the top right hand corner.
Anyway, tonight I had another go at updating and I found the oldest possible driver that had the "fix mouse cursor corruption issue". This also had the stuttering bug and I found this thread:
So I have rolled back again to my original drivers with the mouse cursor problem which seems the lesser of two evils at the moment. Can someone please give a suggestion as to what I am actually supposed to do...?
