--- Comment #4 from Daniel Balog <Daniel.balog at hexagon.com> ---
So I just upgraded to the latest MacOS minor version, and the situation is a bit better. I not get a WebGL Context Lost, which seems to be limited to Safari, and doesn't leak to external applications as it did before.

Specs:

MacOS 13.6.2
Safari 17.1
MacBook Pro M1 Max

Steps to reproduce:

* Open link on MacOS 13.6.2 -> http://demo.luciad.com/SafariCrash/Crash/
* Do not interact with view, let it fully load (This can take a half a minute as it runs on an EU server)
* WebGL Context will be lost + potentially you will see some blocky artefacts on the screen


This issue can not be reproduced on MacOS 14. It seems to be fixed there. 

The issue can be reproduced with the latest Safari Technology Preview on MacOS 13.6.2
