Kristian Høgsberg <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |FIXED --- Comment #5 from Kristian Høgsberg <[email protected]> --- Those touch coordinates in the backtrace look really out of place, that may be a different problem in itself. But there are a few corner cases where we can legitimately fail to touch a surface, so we need to check for NULL in touch_to_activate_binding(). commit 0ed6750541eac94af7083fabe5911c20e6ca31f9 Author: Kristian Høgsberg <[email protected]> Date: Thu Jan 2 23:00:11 2014 -0800 shell: Only assign focus on touch if there is a touch focus surface Similar to 7c4f6cc145daf66cd9624f1e70dd5278241f5858, if we don't have a background image from the desktop-shell client or the touch point for some other reason doesn't hit a surface we trigger a segfault as we try to deref the seat->touch->focus NULL pointer. For touch, another problem could be fudgey calibration that ends up giving touch coordinates outside the output space. https://bugs.freedesktop.org/show_bug.cgi?id=72839 -- You are receiving this mail because: You are the assignee for the bug.
