Does turning off opengl help?

The crash would happen maybe 3 times a day average. It seems OK so far using --opengl=no but I need to test some more. I'll report back.

Probably a flaky opengl library on osx, see #563, #695, #593

Hopefully we can get a more reliable client toolkit in the future, either GTK3 (as per #90) or something else.
Until then, I don't want to start blacklisting every driver.. so I don't know what to do with this one.
@afarr: thoughts? crashes are bad... but the non-opengl experience is pretty bad I think. Which one is the worst?

I regularly force --opengl=on on my osx with an Intel video card... it rarely crashes on me.

Testing with the opengl off, whether with an older machine that just plain doesn't have supporting opengl libraries or with the newer with the blacklist isn't that bad of an experience, overall... but I have a high tolerance for some jerkiness in my video and such.

All told, I don't think the blacklisting is as bad as the crashes... especially if one has the option of "living dangerously" by forcing it on. It is odd though, we have a number of NVIDIA cards around here, and we haven't seen anything near 3 crashes a day. Or at least not that we'd identified, but come to think of it there was a surprisingly quick crash that did involve an NVIDIA card - so maybe the connection just eluded us.

I suspect, by the way, that wireless contributes to the opengl issues on osx... which might be useful for anyone coming across this, but I'm not sure that this helps with finding a solution.

I'll pass this back to you, and leave you to make a final (reluctant) decision.

I guess we could split the blacklist into a greylist so that we start the client with opengl disabled but with the menu option to enable it on the fly, rather than requiring the command line argument.
I'll try to get that in.

Greylist added for Intel (on OSX and win32) and nvidia (osx only): done in r9001. Testing blocked by #724.

Ready for testing: those cards should now start with opengl turned off but with the ability to turn opengl back on from the tray menu.

Tested an OSX (10.10 with Intel, 10.8 with Nvidia) r9116 client(s) against an r9116 Fedora 20 server:

• Was able to toggle OpenGL on the fly from the features menu on both computers. Verified it was enabled and disabled in session info (went from n/a to single buffering)

Worth mentioning #818, painting the spinners with opengl may make the opengl=on more stable.

See #818#comment:10 - let's see how re-enabling opengl works out. (for 0.16)

The Intel driver is greylisted again in 0.16, see ClientRendering OpenGL
