WebGL not enabled - message on Vivaldi 1.13 Linux

jess_robinson995

Hi all,

I was happily using Onshape, using Vivaldi on Linux, up until somewhen late last year.. This year I updated the browser from 1.9 to 1.13, and WebGL in Onshape stopped working..

the spinny box on get.webgl.org is spinning just fine, any ideas?

sad Jess..

Have you experimented with opera, chromium, or firefox?

Jess,

Please try loading https://cad.onshape.com/check. That page runs a few tests for Onshape browser compatibility.

I've also installed the latest stable 1.13 64 bit vivaldi release (1.13.1008.44) on Linux (Ubuntu 14.04 LTS 5), and am able to open Onshape documents. If the browser check page looks OK, are there any errors in the vivaldi console?


Regards,
John de Freitas

Hi John,

That page is fairly negative

vivaldi://flags has : WebGL 2.0 Mac, Windows, Linux, Chrome OS, Android

Allow web applications to access WebGL 2.0. #enable-es3-apis

 .. Enabled

For what it's worth.. google-chrome has a much greener looking webgl "check" page... but still refuses to work when viewing an onshape doc

Hi Jess, 

A few questions :

- What exactly do you see, when you open an Onshape document? Can you post a screen shot?
- Have you checked out some of the troubleshooting steps described here: https://cad.onshape.com/help/Content/webgl.htm
- Do you see any error messages in the Chrome debug console?
- What graphics card do you have? Are the drivers up to date? 
- As a test can you try opening this WebGL heavy page : https://threejs.org/examples/#webgl_materials_cars ?

Thanks
Paul

When I first try and load a document, it does sort of work - it displays the 3 axses, but they are black, the cube that should display top/left/right is also there but unreadable text.. I can hit "top", it attempts to display the top view.. then the whole page says "One moment..." and then this happens:



I cant seem to force it back to that initial "attempting to work" view, I guess its somehow stores the "not working" flag - tried deleting all the cookies and local storage etc, no dice.

I can see shiny spinning cars on the thereejs.org page.

I think Im using the AMD onboard graphics device.. no idea re drivers - lspci says: 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri [Radeon R7 Graphics]

Woo! I turned on Override software rendering list in vivaldi://flags.. and now it seems to be working!



Will see how it goes.. (I wonder what vivaldi changed.. or maybe the underlying chromium did..)

jess_robinson995

Seems to mostly work.. somehow none of the rotate/pan mouse gestures work..

I tried changing the settings in account/preferences - no difference.

Mouse gestures not turned on in browser at all.. odd.

Paul_J_Premakumar

If the software renderer works, I suspect there is an issue with the graphics drivers.

With regards to the mouse gestures, do other browsers have the same issue as well. If this is Vivaldi only, can you try disabling the mouse gestures and then try Onshape? 

Can you also check in the Vivaldi forums to see if they have any suggestions?

The mouse gestures (in vivaldi, for navigating pages) are already disabled.. or did you mean the OnShape ones?

jess_robinson995

Poking graphics drivers...

Meanwhile, tried google-chrome again.. it seems to be fully functioning at the moment - without messing with its settings/flags, it both doesnt complain about webgl, and the mouse works.. 

such fun..

Installed vivaldi 1.9 snapshot just see if that would work.. nope - same webgl issue.. and flags page doesn't load..

jess_robinson995

heh, discovered a new thing.. not sure if this exists elsewhere.. vivaldi://gpu tells me about all the gpu related things. Shame I didnt screenshot it post gpu driver upgrade.. it definitely said hardware acceleration disabled, and WebGL2 not supported... Now it says:

jess_robinson995

The onshape check pages now says:



however.. actual document pages look the same as before - loads with oddly black planes.. then goes to the "doesnt have webgl enabled" popup.. this is with software rendering turned off again, for a test..

jess_robinson995

Story gets wierder.. earlier, just after reboot/browsewr start, I had vivaldi://gpu as shown in image above, now it looks like this:



and the onshape webgl check page is back to red Xs.. is it possible that starting onshape causes my browser to turn off hardware acceleration?

john_f_carr

Some browsers remember if there has been a problem and refuse to use the card again.   In that case the graphics card will appear to work until the first problem, then it will be disabled.

cheeky of em..

I managed to capture what things look like just before onshape gives up:

That 0.2 million triangles a sec reading looks suspect, my crappy on-board graphics gave 17 million, dedicated card gave 380 million...

Looks Cool

how come you've got about 65 tabs open??

Does that improve performance?

That's just how life is.. that's not all of em, there are 2 other windows (tho not quite as full..)
