So if we're not hitting the framerate we want, then assuming drawing takes less time than a frame (which is a reasonable assumption since it's fluid on weston and the drawing isn't different there), we must not be drawing frequently enough. I think these profiles suggest, indeed, the timings are wonky. Can you instrument maybe_start_idle in gdkframeclockidle to print out what min_interval it's using for mutter versus weston ? Does your version of mutter have this commit, by the way? <a href="https://git.gnome.org/browse/mutter/commit/?id=50099c4c10c9311c6d0deb978d21637c9437c027">https://git.gnome.org/browse/mutter/commit/?id=50099c4c10c9311c6d0deb978d21637c9437c027</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
