Comment 3 for bug 989648

This bug might be input driver related. I just tried to minesweeper. In this game, you have to press both mouse buttons simultaneously to clear known-to-be-empty fields. Every 2-5th time, the game does not recognize the button up event. (One can see this because minesweeper shows a different icon while the buttons are pressed. I can not reproduce this in xev, so maybe this is even gnome/gtk specific?)
