[Linux] Any workaround for the double cursor bug in Armikrog?

Armikrog never got a bug fix for a known Unity bug, when system cursor is shown together with custom cursor (on Linux). Is there any workaround for it? It’s a really annoying bug, and it doesn’t look like developers plan to fix it any time soon.

From the game files, it looks like it’s Unity 4.5.5f1. May be there is some custom build that can be used instead of the game binary that fixes this?

Bump. Any suggestions how to hide system cursor when running the game?
