I could imagine that the latency is caused by the VGA port getting polled.

Can you connect the monitor to VGA instead of DVI? This might work around the problem.

When the monitor is connected to VGA, symptoms disappear and according to latencytop, drm_mode_cursor_ioctl only takes a maximum of 5ms.

When both output (VGA + DVI) are connected (clone mode, on the same monitor), symptoms reappears (latency around 100ms).
