I'm trying to record a video of the simulator screen using the following command:

xcrun simctl io booted recordVideo --mask=ignored ~/Desktop/footage.mp4

As you can see, I specified the value ignored for the mask parameter because I want to omit the mask on the iPhone X's simulator.

The documentation says:

For non-rectantular displays, handle the mask by policy:
ignored: The mask is ignored and the unmasked framebuffer is saved.
black: The mask is rendered black.

Here is the result:

enter image description here

As you can see, as soon as I start interacting with the simulator, the mask appears.

Am I doing something wrong? Is this a known bug?

PS: recording from an actual iPhone X is not a solution as I don't own such a device.

While very far from an ideal solution, it might be possible for you to use an adjusted version of the 5.5 inch iPhone App Preview video. The 5.5 inch phones use 1920x1080 so what I had to do was basically squish one dimension to make the video 1920x886 pixels. Of course, it will look slightly squished, but it isn't that noticeable since it is only a reduction of around 20%. I would argue it is better than no App Preview or going through tonnes of trouble trying to borrow an iPhone X series device. At least until the simctl bug gets fixed!
