4 Subject: [PATCH 4/4] weston: Fix touch screen crash issue
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
12 Upstream status: pending
