Weston freeze when using glmark2-wayland at 1080p@60

Hi Guys,

I'm facing weston freeze issue when running glmark2-wayland to benchmark OpenGL.

I attach thread info as see below.

#0  0x0000ffff94bed600 in __GI_epoll_pwait (epfd=<optimized out>, events=events@entry=0xffffefbc8c68, maxevents=maxevents@entr2
#1  0x0000ffff94bed750 in epoll_wait (epfd=<optimized out>, events=events@entry=0xffffefbc8c68, maxevents=maxevents@entry=32, 2
#2  0x0000ffff94ce5100 in wl_event_loop_dispatch (loop=0xaaaaff682ee0, timeout=timeout@entry=-1) at src/event-loop.c:634
#3  0x0000ffff94ce3b3c in wl_display_run (display=0xaaaaff685900) at src/wayland-server.c:1260
#4  0x0000aaaad0f962c0 in main (argc=<optimized out>, argv=0xffffefbc94a8) at compositor/main.c:1919

I guess wayland is waiting the one event status change to WL_EVENT_READABLE, but not changed.

Do we have any debugging trace to get current fd number and know that's task name?

I tried setup the env 'WAYLAND_DEBUG=1', but more events to be find, and will can't to reproduce the issue(Maybe print message post qulickly and render is slow).

Regards, Bettman

Weston version: 4.0/5.0 Wayland: 1.6/master
