Weird Framerate Fluctuations Caused by Mouse Clicks

[vp49p3 216]

Hi-my rig is a 13900k watercooled cpu, 4090 graphics card, 32 5800 speed ram. Monitors are 3 in nvidia surround at 4k and a 1080p touch screen, all four of which are on the Nvidia card.  Two more touch monitors are run off the onboard video.  All monitors work fine.  Lately something weird happens.  If my cursor's on the three in surround I get 50+fps at high settings.  Other three monitors also work fine.  The rig has worked fine for over a month.  But, now if I click on any one of the other three monitors not in surround, the fps on the surround monitors drops under 10fps.  Clicking on the surround monitors again restores fps to 50+.  This just started happening.  Previously it did not occur.

Any ideas on what causes this anomaly and how it can be fixed? It's really annoying as I want to leave my cursor where it was and not have to worry about re-clicking on the surround monitors every time I move my cursor somewhere else.  Also if I don't reclick the surround monitors fast enough sometimes P3dv5.3 crashes.  Any help appreciated!

Never mind.  Fixed it.  The surround display had a different refresh rate.
