I'm sorry, I guess I wasn't clear. The wayland backend is not using async rendering at all. What I meant is that I was testing the software_x11 engine, and I forced it to use the sync path too, just to make sure that it was not a problem related to that and correctly compare it to the wayland backend. Anyway, the software_x11 engine worked on both cases (sync and async), while the wayland backend doesn't work (it only uses sync at the moment). > You really need to check if you are using any async path which I > doubt.

Agreed, wayland_shm backend is not using any async path, although Devilhorns has some patches about to be landed that would make use of the async path. Anyway, his patches also don't fix the issue. > -- Ulisses > >> So I ask you guys if you have any more ideas, even just say "try to >> debug or check this". devilhorns, acidx, hermet, raster? >> >> There are some more details on the ticket: >> http://trac.enlightenment.org/e/ticket/1407 >> >> Thanks, >> -- >> Rafael Antognolli >> http://antognolli.org/ >> >> ------------------------------------------------------------------------------ >> Everyone hates slow websites.
