What opera://gpu says about WebGL?

Had the same problem. It was corrected by ticking the box for hardware acceleration in Settings. I had that unticked for some other reason, which no doubt will arise again and bother me. Curiously, RadioGarden works in Chrome without having hardware acceleration.

Thank you garyallan. I have to admit that when I read your solution I had my doubts. As in, what would hardware acceleration have to do with anything?
But, that fixes it. I have no idea why. Perhaps a developer can explain what is going on. I hate it when I don't understand.
This is a really cool web site! Every radio station in the world.

Maybe because WebGL depends on the graphic card to run?

Well, how does hardware acceleration work? Why isn't everything accelerated to begin with.
I worked for a computer manufacturer many years ago that had a built in accelerator feature. But it cost the customer to activate it. Mainly used during peak periods. I can't imagine my little cpu having that feature.

Hardware acceleration is handled by your graphics card in Opera. If it is a weak or poor graphics card it can have problems performing the task and its best to turn it off. With it off, everything is handled by your CPU instead.

Basically it uses your graphic card to process/render video/image related stuff.

Because not everything can be hardware accelerated. It may depends on the graphic card and OS.

But it cost the customer to activate it.

Hardware acceleration is enabled by default in Opera. At least here on Windows 10.

So, it's really Graphics acceleration. Why not call it that?

LeoCG, if your suggestion were correct, then why does RadioGarden work for me in Chrome without having hardware acceleration? It is all on the same lightweight Acer laptop.

Because everyone knows it by the name 'hardware acceleration' and doesn't make sense try to change it now.

Maybe Chrome doesn't rely on the graphic card to run WebGL.

And unless you have turned it off, Chrome has hardware acceleration too.

Leocg, of course I had the hardware acceleration turned off in Chrome.

I used to be a developer. I find your attitude to be egocentric.

Technically, it's a hardware accelerator device installed in a computer (as opposed to software-coding only), working roughly in parallel with the CPU, and used for or dedicated to graphics acceleration. There are other types of accelerator implementations and usages possible, particularly in servers. Similarly, one can in principle write software-only code to assist in certain kinds of graphics (as well as other forms of) acceleration.

In current language with respect to commercial home computers, hardware acceleration and graphics acceleration have become interchangeable terms, much like the terms 'cars' and 'automobiles'. Frankly, it's not really something to take issue over, though it can be confusing to some or lead to misunderstandings for some folks.

Nope, not really. Cf https://cesiumjs.org/tutorials/cesium-up-and-running/
