crash log

Hi
I am using weston 1.6.0, I encountered a problem with weston running on fbdev
backend after weston prints "unexpectedly large timestamp jump".
for weston, I use animation=zoom, if I use "fade", then there is no such issue.
for client egl applications, I use a script to launch two applications one by
one, the first application draws one frame to the screen and then exits, the
second application draws a very complicated scene that will take more than 2
seconds for GPU to finish.
so when the second application runs, the weston desktop still keeps the first
application's image, and then weston crashes.
I can provide more information if required
