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:

  • @swimboy I'm not seeing such message in that page here. I'm on Windows.

  • @leocg As my post mentions, I am on MacOS Mojave using Opera for Mac and I see the problem. 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.

  • Here no problem to open your linked page. The graphics are visible and the map is zoomable. No pop-up window.
    macOs Catalina 10.15.7, Opera 72.0.3815.148

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

  • @swimboy Do you have hardware acceleration disabled by chance? What opera://gpu and http://html5test.com say about WebGL?

  • @leocg Hardware acceleration is disabled. 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
    Compositing: Software only. Hardware acceleration disabled
    Metal: Disabled
    Multiple Raster Threads: Enabled
    Out-of-process Rasterization: Disabled

    Rasterization: Software only. Hardware acceleration disabled
    Skia Renderer: Disabled

    WebGL: Software only, hardware acceleration unavailable

    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?

  • @leocg
    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?

  • @swimboy I don't have that option here, it should be a Mac specific one. 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.
