It’s been weeks and month but I can’t get the map to work.

I tried all web gl stuff, different browsers cutting all extensions … you name it, but the site always looks like this:

(Image upload doesn’t work - a sign?)

I’m using Ubuntu 22.04.5 LTS

If I inspect the map area this is the html code:

`<div style="position: relative; width: 100%; height: 100%; flex: 1 1 0%;"></div>`

Hi Christian! I am suspecting that our map tool is being blocked from loading. To help narrow down the issue, will you see if any of these map examples are visible for you? [Gallery](https://www.mapbox.com/gallery)

Thanks!

I tested a couple and all of them worked. Fast loading, all controls work without lag and so on…

Good to know. Let’s try something else. Does the map on this page load? [UDisc - The App for Disc Golfers](https://udisc.com/courses/harris-hillside-3zTX/layouts?selectedLayoutId=85497)

Yes it loads fine.

I found a partial solution myself! I took a deeper look at the network analysis and found the following error message:

```auto
Failed to create WebGL context: WebGL creation failed: 
* WebGL 2 requires support for the following features: 
  transform_feedback2 (FEATURE_FAILURE_WEBGL2_OCCL)

```

I don’t fully understand but it seems like an issue between graphic card and on board graphic?

Deactivating hardware acceleration in the chromium did the trick and the map is now visible again but for Firefox it is still the same issue .
