I guess it's
<http://community.kde.org/KWin/Environment_Variables#KWIN_DIRECT_GL>.
kwin on my system use indirect rendering, other applications direct. I'm
not sure why i915 isn't whitelisted.

No, I cannot reproduce it now. From time to time I hit similar problem,
but it's not so annoying (doesn't occur on every screensaver run) and I
hadn't managed to take backtrace yet (stack is corrupted), so it might
be completely unrelated. I'll report it as another bug if I manage to
get more details.
I guess this bug can be closed.
