Vive trackers are shaking in specific places in a room. Sometimes they shake, sometimes they don't. Knuckles controllers are tracking perfectly.

What can be causing this problem? Maybe it's bad USB 2.0 slot quality?
I read that it's recommended to buy some Inateck USB controllers. I need to connect 8 Vive trackers. What USB PCIe card is recommended?
Maybe my room has IR reflective walls? What material should I use to cover the walls so IR signal won't be reflected? I tried to cover one wall (only a part of it) with bedsheet, but did not notice any improvement in tracking accuracy.
I noticed that when I have only two base stations turned on - tracking is much more stable. Maybe Index and Vive Pro base stations are incompatible with each other? (although they look the same visually).
Wi-fi is turned off.
Room is about 5 to 4 meters and roomscale is setup to 4x3 meters. Room has white PVC wall and ceiling panels.
Four base stations (two Valve Index Base Stations (bought seperately) plus two SteamVR Base Station 2.0 from Vive Pro bundle)
Vive Pro + VIVE Wireless adapter ( https://www.vive.com/eu/accessory/wireless-adapter/ )
Eight Vive trackers 2.0 connected to USB 2.0 powered 10-ports hub + eight USB 2.0 extender cables (so dongles are apart from each other at 1 meter distance).
