   4 Subject: [PATCH 4/4] weston: Fix touch screen crash issue
   5
   6 Touch screen operation causes the weston to crash with segment fault sometimes.
   7 The crash occurs when the coordinate (x,y) passed to the weston input module
   8 is outside the view window, hence the weston compositor is not able to pick
   9 up a display view and there is no code to detect this condition at function
  10 notify_touch().

  12 Upstream status: pending
