Workspace larger than screens

[msknight]

Ubuntu 24.04 LTS - Cinnamon 6.0.4 Kernel 6.8.0-40-generic
Graphics card Nvidea 750Ti using nvidea 535 proprietary, tested driver which is what Ubuntu is recommending by the looks of it.

Three monitors which I've attempted to drag in various configurations after reading all sorts on-line. Two are 1080 and one is 4K. The formal workspace area is much larger than the monitor areas, as pictured.

As a result, the mouse can go way off the right or bottom of the actual screens, into dead workspace area, and get lost.

It's a minor annoyance but something I'd like to get to the bottom of, if possible, but some of the things I was reading on-line didn't inspire confidence so I thought I'd ask here.

There was a 550 driver. Switched to that and rebooted - problem solved.
