I tried a few things today: 1) rebuilt all x11-libs, media-libs, and anything I could think of that would be related to x11-libs (such as gtk+, qt...)
2) downgraded to xorg-server-1.5 Neither of these things helped. Alan's hypothesis sounds plausible, but I don't even know which package to point fingers at! Probably it's the Mathematica interface itself, which is horribly old by now, but I cannot upgrade it at this time. As I said, dragging the scrollbar down works fine, but you drag the scroll bar up, and in a few seconds X gets zapped. I tried instead clicking above or below the scroll bar to avoid dragging. That is a tad better, but after a few times, it goes down again... The weird thing is that I never had this problem before doing the massive lib-xcb upgrade, and obviously the xorg-server doesn't seem to be helping or hurting anything, so I went back to xorg-server 1.6. Is there any procedure out there about de-Xifying your system? I don't have the time right now to do all this, but I am just wondering if some people have removed everything X-related from their system and started anew without completely wrecking the box...
