The modesetting driver doesn't allow disabling DRI3 on the server side. You can always disable it on the client side though with the environment variable LIBGL_DRI3_DISABLE=1 . The fps graph shows the same framerate in both videos, so the problem seems rather about animation timing. It might be related to the fact that DRI3 allows triple buffering, and might be at least partially an application issue. It would be interesting though if it also happens with a non-AMD GPU. BTW, is there any particular reason why you're disabling sync-to-vblank? It is the intended mechanism for smooth animation...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
