The fpsVR BETA has been updated with the following changes:
General:
Added an option to force Chaperone to be disabled. This will likely help with VR headsets for which the Chaperone disable option was not originally intended. More details can be found here:

Fixed an issue where the overlay would not hide under specified conditions if the controller position was not linked to the headset or controllers. More details can be found in this thread:

Added the ability to add custom comments for a session in the history viewer (desktop version)/
Proton (Linux):
Experimental support. You can now run fpsVR under Proton. To do this, add the -proton launch key (and only this key) to the fpsVR properties in your Steam library.
Limitations:
CPU/GPU monitoring (load, temperature) doesn't work.
fpsVR autostart doesn't work, start it manually.
The Audio section in the settings doesn't work.
The built-in VR history viewer doesn't work. This is likely a temporary issue, and it will be possible to adapt it to Proton in the future.
The data set variant that is displayed by default in the overlay is disabled. If you select it, the next option on the list is automatically selected. This is due to incorrect rendering. Emulation under Proton distorts the overlay formatting. May need to redo everything.
It's possible that something else isn't working.
