Describe the bug
As instructed by the last comment in #234, I ran the command sudo setcap CAP_SYS_NICE+ep ~/.local/share/Steam/steamapps/common/SteamVR/bin/linux64/vrcompositor-launcher to finish setting up SteamVR. After doing this, the chaperone bounds, along with the empty space (between loading games), and menu. Also, graphical glitches occur. If I undo this command, with the command sudo setcap CAP_SYS_NICE-ep ~/.local/share/Steam/steamapps/common/SteamVR/bin/linux64/vrcompositor-launcher, these issues go away.

To Reproduce
Steps to reproduce the behavior:

1. Execute the command sudo setcap CAP_SYS_NICE+ep ~/.local/share/Steam/steamapps/common/SteamVR/bin/linux64/vrcompositor-launcher
2. Open SteamVR
3. Open menu or make chaperone show, then rotate head and see the geometry lag behind motion.
4. See error

Expected behavior
Menu and chaperone boundaries should keep up with the motion (as all games do, regardless of the setcap).

System Information (please complete the following information):

• Distribution: Arch
• SteamVR version: 1.15.16
• Steam client version: 2020/12/20 23:07:25
• Opted into Steam client beta?: No (same thing happens with beta though)
• Graphics driver version: Mesa 20.3.2
• Gist for SteamVR System Information: https://gist.github.com/Ominitay/e2cd60a8bab4891346012cf0bea954f5

Screenshots
I've yet to set up video recording software. The best way I can describe it is that if I look left, the chaperone bounds seem to lag to the right, and catch back up with in-game geometry when I stop moving my head.

Additional context
This persisted after reinstalling Arch.
