It looks to me like labels are meant to be anchored to objects in the map. In this case, I want to display some text on top of the map all of time.
I want it to be in the webgl itself, not an html element on top of it.

Relevant, but I am not sure if they found a definitive answer: https://stackoverflow.com/questions/49807311/how-to-get-usable-canvas-from-mapbox-gl-js – chriswhong Oct 17 '22 at 12:44

There are probably a million different ways to better accomplish your REAL objective, if you'd only state what that is, but anyway, if you're really determined to do what your question states...
- Make an image with your text.
- Base64 Encode that image.
- Initialize the map with
preserveDrawingBuffer: true(note, performance will suffer) - Use the following code. Replace the long base64 string with YOUR image. Replace the token with YOUR token.
// TO MAKE THE MAP APPEAR YOU MUST
// ADD YOUR ACCESS TOKEN FROM
// https://account.mapbox.com
mapboxgl.accessToken = 'REPLACEME';
const map = new mapboxgl.Map({
container: 'map', // container ID
// Choose from Mapbox's core styles, or make your own style with Mapbox Studio
style: 'mapbox://styles/mapbox/streets-v11', // style URL
center: [-74.5, 40], // starting position [lng, lat]
zoom: 9, // starting zoom
projection: 'globe', // display the map as a 3D globe,
preserveDrawingBuffer: true
});
map.on('render', () => {

Fiddle (you have to change map token in order to see it in action): https://jsfiddle.net/rygj51ca/1/
The above code will render an image of a smiley on the mapbox canvas, bottom left corner, every time the map renders.

If you want text in "the top right corner", then you don't want it in the map at all, you want it over the map.
In that case, the best way is just to use a different HTML element, styled however you like. Along these lines:
<div id="map" />
<div id="text-overlay" style="position: absolute; right: 0; top: 0;>Here's my text</div>

I specifically said I want the text to appear in the webgl itself, not an html element on top of it. I am capturing the webgl to record video and I want the text to appear in the video. – Keith Carter Oct 18 '22 at 22:13

So, you didn't mention the actual *reason* you want this in your question. – Steve Bennett Oct 19 '22 at 00:59

I'm pretty confident there is no way to do this in Mapbox GL JS, so it comes down to hacking the Web GL context directly. – Steve Bennett Oct 20 '22 at 05:09
