--- Comment #19 from Tomasz Figa tomasz.figa@gmail.com 2010-09-14 07:55:09 PDT --- After some additional testing, I can reproduce this bug by opening a PDF document in Okular and scrolling through several pages back and forth, then mouse cursor hangs and X server crashes.
Moreover, I can reproduce this bug with 2.6.35.4 kernel (with 2D corruption patch applied, haven't tried without it yet).
