Mutual brightening with two leapmotions

I have problem when two players look at each other. Mutual IR brightening (constant light and short powerful flashes) causes bad tracking and a lot of bugs.
Is there a way to disable flashing and reduce brightness of IR leds?

No, there isn't. What is the setup here?

Setup - gaming desktop (core i7, gtx1070,..), oculus cv1 and leapmotion with Orion 3.1.2

I meant the physical setup of your project or game. Is this a project where both participants are expected to be in the same room? If so, I'm not sure there is a perfect solution. However, moving the players farther apart will decrease interference. Here at Leap, as you might imagine, we have Leap devices flashing all over the place. I usually only get functional degradation when I am looking at a second Leap device right at my desk. How close are the players when the problem happens?

(The video wouldn't play for me.)

In this projects players are expected to be in the same room end even physically interact with each other. So it is important to have good tracking conditions when players are close.
We noticed strange thing that sometimes everything works well and in visualiser other LM devices look like 3 small bright points (with normal tracking at the both devices). But the problem may appear or disappear without any changes. For example, after restarting of visualiser.

I don't think there is any way to avoid interference when two controllers are close and staring directly at each other. Why the interference may seem intermittent is that the duty cycle of the illuminators is quite small making the possibility of exposure collisions less than you might otherwise expect.
