Cursor disappears sometimes on G command

So, recently in the past month or so, ive been experiencing a bug with the G command. When hitting G and pinging on the mini-map, pinging cooldowns, ping, health and mana, spells used, and other G commands, my cursor sometimes will disappear and i have to reconnect. its a hassle and very annoying. It doesnt always happen, and i can use the g command on my screen in the game, so, any suggestions?
