TL;DR
Users on Reddit report that Quest Pro headsets, when used with Virtual Desktop and Vive Trackers, are spawning tracker points below the floor level. This unexpected behavior could impact VR tracking accuracy and system reliability.
Multiple users on Reddit have reported that when using the Quest Pro with Virtual Desktop and Vive Trackers, the trackers are appearing beneath the floor level, suggesting a possible tracking calibration or software glitch. This phenomenon raises concerns about tracking accuracy in VR setups that combine these devices, which could affect user experience and system reliability.
According to posts on r/Vive, users are experiencing a bug where Vive Trackers, when used with the Quest Pro via Virtual Desktop, spawn below the virtual floor plane. This issue appears to occur during specific configurations, particularly when multiple trackers are used simultaneously.
Some users have noted that this behavior results in inaccurate tracking, with virtual objects or controllers appearing to float beneath the floor, potentially disrupting immersive experiences. For troubleshooting, see HTC Vive detection issues. The problem seems to be linked to how the system calibrates or interprets spatial data from the Quest Pro and Vive Trackers.
There is no official statement from Oculus or HTC Vive at this time, and the reports are currently anecdotal, based on user experiences and screenshots shared on Reddit. It remains unclear whether this is a software bug, a calibration issue, or a hardware compatibility problem. For more VR troubleshooting tips, visit our homepage.
Trackers Spawning Under the Floor
Reddit users report that Quest Pro headsets running Virtual Desktop with Vive Trackers are spawning tracker points below the virtual floor plane — a glitch that threatens tracking accuracy, immersion, and full-body setups.
The Signal Chain Where Things Break
Advanced PCVR users combine three ecosystems in one pipeline. Somewhere along this chain, spatial calibration data is being misinterpreted — and trackers land beneath the floor plane.
Quest Pro
Meta’s mixed-reality headset streams PCVR content wirelessly from a gaming PC.
Virtual Desktop
Bridges the Quest Pro to PC-hosted VR, relaying pose and spatial data to SteamVR.
SteamVR
Composites headset, controller, and external tracker positions into one playspace.
Vive Trackers
HTC’s body-tracking pucks — reported spawning below the floor level.

Anatomy of the Floor-Spawn Bug
What users on r/Vive are actually seeing — and why it matters beyond a visual oddity.
Below-Floor Spawning
Vive Tracker points appear beneath the virtual floor plane at session start, instead of at their real-world height.
Floating Virtual Objects
Controllers or tracked props render sunken or floating below the floor, breaking the alignment of the whole environment.
Multi-Tracker Setups
The behavior shows up most often in specific configurations — particularly when several trackers are used simultaneously.
Broken Immersion
Misaligned playspaces make full-body tracking feel “off,” disrupting experiences that depend on precise positioning.
Unreliable Spatial Data
In professional and dev environments where accurate spatial data is critical, the glitch can invalidate sessions entirely.
Discomfort Risk
Misaligned virtual environments can contribute to motion sickness and user discomfort during extended use.

Implications for VR Tracking Accuracy and System Stability
This issue could have significant implications for VR users relying on precise tracking, especially in professional or development environments where accurate spatial data is critical. If trackers are spawning below the floor, it may lead to misaligned virtual environments, motion sickness, or user discomfort.
Developers and enthusiasts are watching closely, as this could indicate underlying bugs in the integration of Quest Pro with PC-based VR systems, or a need for firmware or software updates to correct calibration processes. The problem also highlights potential compatibility challenges between different tracking systems and VR headsets.
Background on Quest Pro, Virtual Desktop, and Vive Trackers
The Quest Pro, released by Meta, is a mixed reality headset designed for both virtual and augmented reality experiences. It supports PC streaming via Virtual Desktop, a popular app that enables wireless connection to VR content hosted on a PC.
Vive Trackers, developed by HTC Vive, are external tracking devices used to enhance positional tracking in VR setups, often employed in professional or immersive applications. Combining these devices is common among advanced VR users seeking full-body tracking or precise spatial interaction.
Recent updates and user reports have highlighted various tracking calibration issues, but the specific problem of trackers spawning beneath the floor appears to be a new and unusual behavior, not widely documented before.
