Questions about OpenGL

[Julien Nabet]

Hello,

During QA activity, I've noticed more and more bugs (including about 
crash) which involved OpenGL. In general, I advise to upgrade graphic 
driver first, then ask to provide opengl_device.log if the bug is still 
reproduced.

But there's also perf pb (see tdf#101162), whereas it should be bring 
better perfs.

So here are some questions about OpenGL part in LO:

1) Are there people which may help/put on cc about these bugs?

I found no one on https://wiki.documentfoundation.org/FindTheExpert

2) What about graphic card driver version/env blacklist politics?

I mean, I pushed this patch 
https://cgit.freedesktop.org/libreoffice/core/commit/?id=ecaabbf527f6f6207ce1ca8924708d23e6db45f5

(blacklist Intel HD Graphics 630 for non minimal version)

and there's another one in review 
(https://gerrit.libreoffice.org/#/c/49186/) which would blacklist 
completely the graphic card since even with the last version of graphic 
card driver, it crashes.

Should these blacklist items must regularly reviewed and so we should 
ping reporters to know if it's better with a graphic card driver upgrade?

Eg: once a year, ping reporters and ask them to upgrade their driver and 
give a new try?

I don't think it's realistic but don't know how to deal with this.

3) crashreports may show opengl part but how to know if it's due to a 
buggy driver or due to OpenGL implementing LO part?
