Seeing opengl errors when forcing opengl=on with Intel 4000 video card #1358

totaam · 2016-11-16T03:03:39Z

Issue migrated from trac ticket # 1358

component: client | priority: minor | resolution: wontfix

2016-11-16 03:03:39: afarr created the issue

Testing with 1.0 r14397 win client, with intel 4000 graphics and --opengl=on, against a 1.0 r14404 fedora 23 server, I'm again seeing opengl errors.

Also seeing with 1.0 r14430 fedora 23 server, both with 1.0 14416 win client and 1.0 r14111 win client. I'll test further back when I can carve out some fun regression testing time.

While testing with the 1.0 r14111 win client, I did notice that it was resizing that triggered the errors...

Server side (with -d stats,compress,x264, and also capturing client) errors (from initial posting in #1111, 1.0 r14397 win client and 1.0 r14404 fedora 23 server):

Per question from out of memory / gl_paint_planar error and eventual client crash #1111 - no r14405 doesn't seem to help with Error 1286. (Errors with all the versions mentioned in this ticket correspond to the ones originally reported in out of memory / gl_paint_planar error and eventual client crash #1111.)
I'm not sure what you're asking with "Does it ever render anything with opengl enabled on this chipset / driver version?" ... it renders, but there are errors all over the logs - there weren't errors all over the logs a few hundred revisions back... so I'll have to go back until I find one that isn't having issues, though I may have to roll server back too, I'll check into it soon.
The Intel driver I'm using is definitely greylisted... so it is only when I force the opengl that I see this issue (which I do regularly not only because I like causing errors, but because it hadn't been causing so many previously).

The text was updated successfully, but these errors were encountered:

As of r14431, this error should be converted to a warning and we will try our best to continue to paint the window (and hope for the best.. it may still fail, just later).
Let me know if that makes things worse - the window may show undefined contents instead of the white background we normally paint onto.

Found a similar question on the pyopengl mailing list: GL error on mac after using pyinstaller, suggests moving the glclear earlier but we can't..
We could try a glflush, or just retry somehow.

Same problem reported here: OpenGL invalid framebuffer operation after glClear(GL_COLOR_BUFFER_BIT)
It really looks like a driver bug: Invalid framebuffer operation after glCheckFramebufferStatus: I am getting a weird OpenGL error when running my application on my HD4000 ... Bind the second FBO and call glClear. The glClear gives an GL_INVALID_FRAMEBUFFER_OPERATION ... We reported this issue to Intel and it seems that it was in fact a bug. It is fixed in the current driver version.
That's almost identical to what we do: double-bind, Intel HD4000... driver bug!

it renders, but there are errors all over the logs..
[[BR]]
That's odd, the error should stop it from painting.
Maybe the error gets caught, we then send the failure to the server and the next screen refresh fixes it (as the call to glclear eventually succeeds) - which is very inefficient.

PS: this bug may have been uncovered by #1232 as the opengl client now uses two buffers by default since r12878.

Odd.

Re-testing some with 1.0 r14111 client against a 1.0 r14430 server... the error does indeed stop it from painting. Potentially even more interesting, with that combo it triggers extremely easily, start some video playing and re-size the window... BUT, if I disconnect and then reconnect to the same server session/instance - I can't repro the bug at all.

Re-re-tested with the 1.0 14416 client, and I'm seeing the same behavior as with the r14111... so I'm going to guess that all the red of those errors was fixing my attention, and when I re-connected I saw video/painting... and that I was wrong in general when I said it rendered (which is a point for sanity, so there's that).

Re-reading this, I notice that my r14430 server seems old even though I built it today... only to notice that I'm getting errors connecting to your svn (one revision short of being able to test that fix...).

I'll test some more later, but post this comment just to clear up the confusion of my mistake about the continued rendering.

Tested again with 1.0 r14448 win32 client against 1.0 r14449 fedora 23 server... no luck or change.

Tried on a client (same versions) with a non-greylisted video card, unsurprisingly there are no errors with working opengl drivers.

Passing this back for you to decide what to do with this awful Intel driver.

I am quite confident that this is not possible. I even wrote a test script to make sure that the GL error is caught as regular "Exception".

As per comment:1, the original exception reported in this ticket should now be logged as a warning instead, though it may still fail, just later, in which case the error will be slightly different.
Edit: it is, see #1364#comment:1.

Please also include the gl_check output so we can try to blacklist this particular driver / hardware combination.

PS: we could also enhance the gl sanity checks to do an FBO glclear test, but this is not without risks - this can also crash, or not trigger the problem: #1367.

Finally carved out a quick minute to re-test. 1.0 r14492 win32 client against 1.0 r14496 fedora 23 server.

You're right, there were some new warnings... before the same old ones were triggerd, and the video froze.

A sample from the client side, where it looks like it tries 3-6 times to hand out a warning and move on before the errors trump the warnings.
