Dear Weston devs:
Sorry for the bothering in when weston-5.0 is approaching, but I am stuck
in the project for three days I need some one's help very much.
I have a widget implementation of shell widgets that destroys the
weston_view
when pressed Esc. The widget is implemented in wayland EGL. Here is the
view_destroy code.
void
twshell_close_ui_surface(struct weston_surface *wd_surface)
{
struct weston_view *view, *next;
wd_surface->committed = NULL;
wd_surface->committed_private = NULL;
wl_list_for_each_safe(view, next, &wd_surface->views, surface_link)
{
weston_view_destroy(view);
}
}
The weston_view is destroyed but the the buffer in the last commit was not
released and the done event was not sent to the widget. When I triggered
the event to show widget again, the client was stuck in EGLSwapbuffer. I
found out about this by using WAYLAND_DEBUG env variable, I hope to the
way to release the buffer after umapping the weston view. Thanks very much.
Regards,
Sichem
