WebGL problems

sören_svensson

The last few days onshape has crashed WebGL on a regular basis. I usually use Opera (58.0.3135.90), but I've tried Chrome (72.0.3626.121) and FireFox (65.0.1) with the same result. It's not just a specific document, it happens on all of them. Other sites like webglsamples.org works just fine in another tab until onshape crashes webgl.

Have you checked for graphics driver updates ?

sören_svensson

Yes, I've tried both newest and old drivers. I even tried with another graphics card. I run Ubuntu 18.04 with an Nvidia 560Ti card.

I notice if I have youtube or some other webgl running in another tab it can cause lag and other conflicts. I assume you have also tried with a single tab?

sören_svensson

Yes, I have. No difference :-(

john_mcclary

are you using proprietry drivers or nouveau?

I'm seeing turning off hardware acceleration in chrome settings helps people. (kind of defeats the purpose IMHO) 

sören_svensson

It happens with both nvidias proprietary drivers and the nouveau. I haven't tried turning off HW acceleration. I can try it as a test but not as a solution.

At this point I would recommend contacting support within the document, they can get more meta data and see if there is something deeper that the basic stuff we can recommend on the forum

sören_svensson ,

 A few things to try out 

1. Can you open the graphics compatibility page and paste a screen shot : https://cad.onshape.com/check ? 
2. On Chrome can you open chrome://gpu/ and send us the result?
3. When you experience the crash, do you see any JavaScript console errors in your browsers console window?

sören_svensson

Here are the 2 first ones, I'll send 2 & 3 when it crashes again.

@sören_svensson  - does the issue always occur with the same Onshape document/tab?  If so, it's possible that there is something specific about the document that is causing a GPU issue (e.g., exceeding a memory limit).

sören_svensson

No, it doesn't matter which document (and they're all pretty small). Here's an example https://cad.onshape.com/documents/a5325a5e3e745da1d2fea385/w/c249d941c23c0dc20de9ce43/e/ba7995ce1c3f198f6cc0fcba

I have been getting some WEB GL issues from my students who just got brand new chromebooks. When I clicked on the Web GL error icon for more info, I ran the suggested diagnostic and it came up with this flag (see attached). Seems like it could be wifi, but I have a feeling it is something with chrome settings, as older Chromebook in my level two second year class are not presenting with any issues, as they used Onshape all last year. These issues are with brand new chromebooks, brand new students, so could be new Onshape settings, new chrome browser settings, or something with the new devices. I can not do Chrome://flags to check software rendering, as that has been admin locked.
