<![CDATA[Opera excluded by mapping software]]>Using Opera 71.0.3770.271 on MacOS Mojave
On the St Albans local newspaper website, I try to open a graphical display including a zoomable map. I get told I should use a modern browser! Safari works.
The website/page is https://www.hertsad.co.uk/news/herts-coronavirus-stats-show-mixed-picture-1-6892674.
Is there something I should do to make these displays visible?

This is what is shown in Safari:

If the dedicated GPU is better, you may try using it.

As far as I know, WebGL depends on hardware acceleration, so it being disabled caused the message on the page.

Unless you are using a very old computer or one with a weak hardware, I don't see a reason to not have hardware acceleration enabled.

I've altered the Opera 'Settings' to allow hardware acceleration and the problem has resolved itself.

There is a nearby option :
"Allow use of computer's dedicated GPU". This is currently OFF. Should it be ON?

I believe that I had turned off the hardware acceleration because it created problems for some websites (though I cannot immediately recall which ones). What are the relevant arguments?

I'm not familiar with 'html5test.com' but it tells me that WEBGL and WEBGL2 are both ticked. The other link produces the following:

Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable
Flash: Software only. Hardware acceleration disabled
Flash Stage3D: Software only. Hardware acceleration disabled
Flash Stage3D Baseline profile: Software only. Hardware acceleration disabled

Problems Detected for Hardware GPU
Gpu compositing has been disabled, either via blacklist, about:flags or the command line. The browser will fall back to software compositing and hardware acceleration will be unavailable.
Disabled Features: gpu_compositing
Log Messages
GpuProcessHost: The GPU process crashed!

Does this offer a clue?

What opera://gpu and http://html5test.com say about WebGL?

That leaves "Mojave" or operator error! Can anyone try this with Mojave, just to twist the knife?

The graphics are visible and the map is zoomable. No pop-up window.
macOs Catalina 10.15.7, Opera 72.0.3815.148

You have confirmed that the problem is not in Opera for Windows. I have confirmed the problem is not in another browser (Safari). What we need, to avoid suggestions of operator error, is for someone using Opera in a MacOS to attempt to reproduce the problem.
