Keyboard is connecting and sending to clients, but not mouse

[clemon79]

Not sure what happened here.

Two Windows 11 and one Windows 10 machine, moved from 2.3(.1?) to 2.4 in an effort to address another issue I was having with a Windows key randomly sending on one of the W11 machines. (I may have tracked that back to a rogue USB keyboard dongle.) Now, my hotkeys (and screen edges) still work to send control from my server to the client machines, but once control is passed to the client machines, only keyboard control passes, and the mouse cursor appears to get trapped in the lower right corner. (That said the log reports the entry point as (3071, 1727) which is certainly not the lower right corner of a 4K monitor., though if that's taking 125% scale into account it sure could be.) Hotkeys do still work to pass control around, including back to the server, where mouse control once again works (of course, since it has hardware mouse control).

I tried setting the High DPI scaling override in Compatibility properties for barrierc on the client machines and same for barriers and barrierd (just to cover myself) on the server, but that doesn't seem to have helped. Don't wanna file as a bug until I know it is actually in fact a bug and not just something simple I'm missing. (EDIT: Also tried checking the Program DPI checkbox as well. Nope.)

Any ideas?

(ONE MORE EDIT: Returning to 2.3.4 does resolve the issue, but since I seem to be able to go back and forth freely I'm happy to help troubleshoot if it helps others.)
