1176046 - Extremely poor canvas performance on Ubuntu 14.04 (maybe other linuxes too)

Status: RESOLVED WORKSFORME

(Core :: Graphics: CanvasWebGL, defect)

Description

[Vick Eit]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150511103818

Steps to reproduce:

Possibly related to this bug here: https://bugzilla.mozilla.org/show_bug.cgi?id=561361

But I have ubuntu 14.04 and am having very poor performance on Canvas. Test case is this demo from Microsoft Edge: http://dev.modern.ie/testdrive/demos/assassins/

Testing this in Google Chrome we see it runs very smoothly. In Firefox though it is very poor.

Canvas used to be smooth back in Firefox 18

Here's a simpler test case: https://installations.tigoenergy.com/base/main/summary?sysid=331

Click on that group of solar panels and move them, you'll see its very bad in Linux, but on Windows its smooth. Here's gif screncast of windows: http://i.imgur.com/FsTYa2O.gif

That's response is incorrect. Azure is a replacement for the thebes wrapper, not cairo.

It's better to have only one test case per but because each test case can have a different problem which needs a different bug.

Going forward we should focus on the original test case from the bug reporter.

This demo is taking over 5 minutes to load on my machine. We're in the process of updating to GTK3 which should help us if this is a WebGL demo.

Thanks Benoit, actually I dont think it is WebGL. Vick Eit is a person at my new job and that link to TigoEnergy is the original place we had canvas issues. We then tested other things and found that demo worked great in all browser on Linux except recent versions of Firefox. My friend booted an old version of Firefox it was 17, and the TigoEnergy canvas issues werent there.

According to the information text below the link to launch the game it does indeed use WebGL.  It loads quickly and performs well here with Firefox 39 on Ubuntu 14.04.2 with a 3.16.7-based kernel.

Can you post the output of glxinfo | grep OpenGL

Here's mine.

It sounds like this ended up working for people.

Let me know if it's still a problem!
