Speckles on Android


I’ve had a few users point out that on Android devices that they’re getting a speckly ‘snow’ on the image. Please have a look at the images below. Any idea what this could be?

Thank you.

Any thoughts on this, @Mr_F?

I’ve created a github issue for this: https://github.com/playcanvas/engine/issues/728

Do you have details about specific Android devices that show this problem. It would help to know models so that we can see which GPU they have.

If users with problems could send a screenshot of http://webglreport.com/ content, would be very helpful.

Hi guys,

Just finding out models. One was the HTC One M8.

Also, as part of our testing, someone had a portrait monitor. In chrome, non-vr, with 4 portrait 1080p monitors, 4gb GTX670, they get 1 frame every 3 secs.

How can they get the WebGL report?

To get webgl report, using the troubling device go in browser to: http://webglreport.com/ then screenshot that page, and send us a screenshot.

Regarding GTX670, did he run PlayCanvas app stretched on all 4 monitors? That is a huge fill rate to deal with.
One important thing is to make sure browser is running using Nvidia GPU, and not integrated Intel card - this can be checked in nvidia control panel settings, there are settings per application, make sure nvidia is set, if changed don’t forget to restart browser.
Make a screenshot of webglreport website on that machine as well.

“lol, no, not stretched, over 4 screens (however, i just tried that, and it looks lot more immersive, and a lot slower!), window size seems to have minimal affect on the framerate, but a small/tiny window gets the framerate into the 10’s.
and no, not using integrated gfx, (i think that would not be possible running on 4 x portraits, integrated cards have a max of 2 ports) … anyhoo… here is the webgl report …”

That looks like it’s using Chrome’s built in software renderer so you’re not getting any hardware acceleration. Hence the low framerate.

Maybe a case of updating the drivers?
