2025-04-27: The way I play VR games wirelessly on Linux e.g. from Steam is to use WiVRn (a fork of Monado) via the Envision orchestrator.

Here's the path I followed to get it working with my Meta Quest 3S:

Download the appImage as linked from the Envision page of the Linux VR Adventures wiki.
Launch Envision from the terminal (so that you can see its console messages). In the GUI at the bottom is a combo box. Select WiVRn as the desired system. Then at the top of the GUI is a button to configure and build it. You will likely need to apt install some prerequisites first. (2025-04-23) Envision wanted me to installed these packages for Lighthouse profile:
```
sudo apt install libeigen3-dev glslang-tools glslc libbsd-dev libdrm-dev \
    libusb-1.0-0 libusb-1.0-0-dev libx11-xcb-dev libxcb-
```

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
