Not really sure, but might be related to the scalable HUD, try to switch to EdgePeek by clicking the mouse wheel when you use menu screens, that’s more comfortable anyway.
Just checked this, but can’t replicate the issue here. You should see a vorpX cursor normally since the game cursor can’t be stereofied. If you see the normal game cursor instead, try to press ALT+C. That’s pretty much the only potential issue I can imagine.
Apart from that, please try to reset both the game settings and the vorpX profile to default (in the config app). That can never hurt.
