           Summary: Some issues when running an embedded westion session
                    inside weston
          Severity: minor
    Classification: Unclassified
                OS: Linux (All)
          Reporter: vebveb at hotmail.fr
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: weston
           Product: Wayland

When running a weston session inside another weston session, there are some
event handling issues.


One simple test is to open weston-terminal in the embedded session:
. type a long sentence
. keep backspace pressed to suppress everything.

You expect to see every letter disappear one by one, but you don't: you unpress
backspace and everything has disappeared at the same time.

Then do the same thing, but with moving the mouse when suppressing the
sentence: you see every letter disappear one by one, everything works as
expected.

A second test is to run weston-gears inside the embedded session.
In the top session, open weston-terminal and type something in it.
The embedded session looks freezed, and when the mouse return onto it,
weston-gears starts again and the terminal shows that some frames are missing
(you didn't hit 60fps).

If you run weston-gears with WAYLAND_DEBUG, there are no issues. Same if you
launch weston-simple-egl or weston-simple-shm at the same time.


This bug was discovered when using Wayland 1.2 and Weston 1.2 (The bug is still
here with Weston git)
