Yes. I have the same problems. I play dota2 to.
AMD, fix it place. Due to this problem I cant use your devices. Its a very important bug.
And i may tell you more.
I have 2 monitors. At monitor A Im playing dota2. After Ive got this bug and close dota2 - I have no cursor on the monitor A. On the monitor B it's ok, cursor displaying correctly. But there is no cursor at the monitor A. I can see visual effects of elements on the desctop when "hidden" cursor hovers them.
Also, if I'll activate "cursor shadows" at windows settings - I'll see broken cursor (I still cant work with it).
I have AMD HD 5830 device, Windows 7 and 15.20 Catalyst.
Sorry for my bad English. I hope, You'll read my post and fix this bug. Contact me if you need more details. For example, I can to record video with consequences of bug.

I have found a little bypass for the problem... I wish AMD will fix but this works for now.
Open Dota 2 in borderless window
open magnifier at 100% and minimize
(someone made a little software to do this without magnifier on reddit just seach "Fix" for AMD video cards cursor corruption')
works for now AMD please fix it
