Can't reproduce with local asan build or following the reproducing instructions (https://docs.google.com/document/d/15ZqPDlz3a8Ac08uWWBc-tM4IZzhP-kYEuQAXiJRiH24/edit#heading=h.uoltawkpum5p).

on clusterfuzz this is still reproducing. Maybe only reproduces in xvfb ? Marty, can you please add the Xvfb command from startup script, i have trouble reaching it (ooo).
These are the commands we're using to set up xvfb and blackbox:

Xvfb :1 -screen 0 1280x1024x24 -ac -nolisten tcp
DISPLAY=:1 blackbox
Using xvfb and blackbox, still can't reproduce locally.

Also the run_gestures_on_device_local.py seems to already start xvfb and blackbox.
