> Did not change anything here (that is with ati card/catalyst)

"Older"™ Catalyst drivers (most of those before 9.0, as reported by the ati
config tool) "legally" use indirect rendering because of various reported bugs.

It seems indirect rendering broke "somewhen" (in either kwin or mesa or
wherever) and the (i hope: falsely) acquired indirect context only exopsed
that.
The "patches" from comment #21 or #22 should on the i830 chip lead to a direct
context and a working system. Same for the OSS radeon driver.
...Hopefully.

No, you are.
At least it seems every driver that has GLX_ARB_create_context (presumingly:
*all*) and calls it with the "legacy" attribute list might struggle on this by
getting you an indirect context (doesn't happen on the nvidia blob, but afaics
the blob simply never creates indirect contexts in the first place)
