Linux Iron 20.0.1150.1 webgl broken

Postby faucon50 » Fri Jul 20, 2012 3:37 pm

Hi,

I posted the problem in the section Iron linux download and it was probably wrong, anyway. Seens this last version I have no webGL anymore. When I try a webGL a popup window says your browser doens't support webGL wich whas not the case with the version 19! Here is my setup:

Xubuntu 12.04 LTS
AMD Radeon HD 7750
Catalyst 12.6 (from AMD)

This are the errors (xsession-errors)

ERROR:command_buffer_proxy_impl.cc(126)] Could not send GpuCommandBufferMsg_Initialize.

(syslog)

(log message in about:gpu)

GpuProcessHostUIShim: GPU Process Crashed.

How can that be fixed or if not, how can I revert to Iron 19?

Thank you.

I found the workaround, launch the browser with the flag: disable-gpu-sandbox and webGL works again.

Please fixe it because it as already been fixed in chromium:

Thank you.

Hi, thanks for reminding people to check the status of Iron's webgl on linux. However, your issue couldn't be reproduced here. WebGL is working just fine with latest Iron on linux (on a laptop with nvidia) without the --disable-gpu-sandbox flag. Below are the relevant flags that needed to be enabled to have webgl working here:

- Override software rendering list
- GPU compositing on all pages
- Threaded compositing (default)
- Enabled accelerated CSS animations
- GPU accelerated SVG and CSS Filters
- Per-tile Painting

Use the about:flags URI to check/change settings.

Hi,

Thanks for your answer. I had this setting already enabled and I tryied without --disable-gpu-sandbox this morning and this flags:

- Override software rendering list
- GPU compositing on all pages
- Threaded compositing (default)
- Enabled accelerated CSS animations
- GPU accelerated SVG and CSS Filters
- Per-tile Painting (this one I'm not sure about because Iron is in french by me. Is this option just upon the one for experimental JavaScript? If yes, it's enabled too.


I could use openGL without the page crash that says: Aye aye aye! the page thoesn't repond anymore... But there is no GPU acceleration and the GPU crashed with:

localhost kernel: [ 3107.434313] iron[8096]: segfault at b6ff05b ip 00007f2abd22eed6 sp 00007fff618ed6b0 error 6 in iron[7f2abbc7a000+482b000] (syslog)

ERROR:command_buffer_proxy_impl.cc(126)] Could not send GpuCommandBufferMsg_Initialize. (xsession-errors)

GpuProcessHostUIShim: GPU Process Crashed. (about:gpu log)

If it works under Nvidia, it seems to be related to AMD driver that behaves in an another way? Anyway, with the --disable-gpu-sandbox I have no crashes and fine GPU acceleration. It would be good if somebody else with an AMD gpu could try to see if it's AMD related or my system.
