[GAMEPLAY] Rek Sai Cursor Bug (Graphics Glitch)

During the game, and more specifically, during the use of Rek Sai tunnels multiple times, the cursor will disappear and become a set of boxed lines making it almost impossible to play, or use your mouse. The bug happens 80% of all games I play with Rek Sai, and will mostly occur after level 5, when I have backed and stated to use tunnels a second time. It has been mentioned before that this is similar to the old Dominion bug that caused cursors to disappear around capture points and then fail to come back until after a prolonged period of time (20-30 min sometimes), or at worst, until the computer had been reset. It has also been noted that Radeon graphics cards could be the issue. I really don't want a third party cursor. Please help fix this, or provide some kind of better work around.
