1298333 - Rendering broken after enabling OpenGL acceleration

Status: RESOLVED INVALID

(Core :: Graphics: Layers, defect, P3)

Description

[Marco Castelluccio [:marco]]

Firefox isn't rendering anything anymore (the window is completely gray), I've found a regression range with mozregression:
https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=8ef9629d8f90d6507b1bad01146b14101de79174&tochange=30fa88c82366a358f412ca2cc3268142c8991f0d

I can see the rendered content briefly when I close the window.

The gfx card is an "AMD Radeon HD 6310 Graphics", with driver "4.3.12798 Compatibility Profile Context 8.96.7".

Ubuntu Precise Pangolin with kernel 3.2.0-109.

Proprietary driver for your GPU is obsolete. Open source driver is recommended for VLIW-based GPUs by AMD. If possible, update to newer distribution (fglrx will get automatically uninstalled while upgrade to 16.04).

This is the standard configuration on 12.04, if we can't support the driver we should blocklist it.

In 2012, I think hardware acceleration wasn't even enabled in Windows.. 
Then, besides, why aren't you *at least* using updated drivers?

I don't know if newer fglrx is okay, but there have been plenty of releases since.. what's that? Like the default catalyst 12.4?

I'm using the latest drivers available in the 12.04 repositories.

But it doesn't really matter, even if they weren't the latest available drivers on 12.04, we should not enable hardware acceleration for configurations that aren't supported. We have a way (a blocklist) to block hardware acceleration for broken drivers, why shouldn't we use it?

Anyway, I believe this will be fixed with bug 1294232. I will retest after bug 1294232 is fixed.

Blacklisting is *how* you fix the problem, but I think we should first try to understand **what** (or where?) is the problem. 

I guess we can all agree in that state configuration isn't supported, but if that wasn't latest driver (like it really seem http://it.archive.ubuntu.com/ubuntu/ubuntu/pool/restricted/f/fglrx-installer/), there still a chance?

I just tried on your same gpu with latest fglrx (4.5.13399 Compatibility Profile Context 15.201.1151)
I get a Can not find symbol EGLImageTargetRenderbufferStorageOES error on terminal, then as soon as I choose "start" on the profile window, the process closes.

Comment 7

[Marco Castelluccio [:marco]]

Would this error be fixed by blocklisting?

Comment 8

[mirh]

I now tried by main firefox profile (rather than my empty testing one)... And for no reason firefox can start. 
And the crazy thing is that I then copied the whole working profile folder to the crashing one.. And it still crashed. 

Is there any other "personal" directory aside ~/.mozilla/firefox/*profile_name* ?

Also, I just checked info about this EGLImageTargetRenderbufferStorageOES https://www.khronos.org/registry/gles/extensions/OES/OES_EGL_image.txt
It states that when OES_framebuffer_object ext isn't available the aforementioned operation is invalid. 
So... at least this error (warning?) I get in terminal (that may or may not be related to the crash and to your rendering problems) seems a thing from the firefox side.

I have a related issue on the latest Nightly with an ATI R7 390 card with fglrx 2:13.350.1-0ubuntu0.0.1 driver.

Which (hoping I haven't misunderstand fglrx_drv.so) is what everybody else knows as Catalyst 14.4
... 

why don't you people update your drivers?

We're testing with the default configuration of the distributions, which
is what a lot of people use, to make sure they work.
When they don't work, we need to decide between blocklisting/fixing the
issue (I would expect these drivers to be blocklisted, since they're
so old).

Comment 12

[mirh]

Ok, that sounds fair. 
But I guess you'll have to decide which fglrx versions to blocklist sooner or later. 

And then, should you discover critical bugs are still a thing in latest 15.x branch.. What was even the point in the "accurate" testing?

Comment 13

[Andrew Comminos [:acomminos]]

Yes, we could fix this by blocklisting. I'd like to know first whether a "modern" fglrx driver works; we have some very old workarounds for fglrx in our GLX context provider whose assumptions may be incorrect now. Unfortunately, I don't have an AMD card to test on.

Linux acceleration is nightly only.

Comment 15

[Julien Cristau [:jcristau]]

nightly only bug, moving to 53

After bug 1323284, acceleration is off by default in nightly as well.

Comment 17

[mirh]

I hope this may be re-opened once you find the manpower to dedicate to gpu acceleration.

Yes!  It was a difficult decision, but we couldn't get it past nightly, and we couldn't keep it just on nightly for any longer.
