Edit: I’m glad so many of you have had no issues with multiple monitors. My set up is a little unusual (3rd display is an infrequently used large tv hooked through the receiver) and is definitely solveable but will take some effort (and honestly, I’d rather spend my spare time outside or with friends, so who knows when I’ll fix it.)
There is not really a solution that I know of, though truthfully Windows still doesn’t handle that in a bulletproof way either as I have a similar situation and both OSes have problems in this regard. I use both Windows and Linux for work at the same time (dual workstations for different orgs that need to be completely separate) and the Windows machine does the whole “app scramble” to a single screen about 1/3 of the time. If anything, having Linux be completely consistent is more helpful as I am ready for it.
