I have a similar issue. Although I'm not experiencing any delays, I lost my 3 monitor setup. 2 monitors are connected on on Radeon GPU and another one on a second Radeon GPU. The second GPU is not activated at all (although during boot it is initialized).

I cannot find something there but maybe someone more experienced can.
Preferred FOSS Xorg drivers have been transitioning[1] from discrete gfxchip-specific to the generic modesetting driver that was moved from a separate package directly into Xorg back in server 1.17. You might try uninstalling the AMD/ATI/Radeon driver (xf86-video-ati) to see if automatic use of the third display is restored by the consequent automatic employment of the integrated Xorg modesetting driver with non-ancient, non-bleeding edge gfxchips.
