Linux was so unable to handle my 3 Monitors (granted, all with different Resolution and refresh-rate, but still) that i had to switch back to Windows today.
gnome-shell started crashing, Firefox and Gnome-Web started crashing for whatever reason. it was a Mess.
Some of that is on GNOME. I had to swap back to KDE after a couple years on GNOME due to lack of VR compatibility. GNOME is good for newbies and productivity, but completely unusable for gaming.
No offence, gnome is great, but there are many inconsistencies on the lover level, I wish it was figured out once and for all. It applies to big DEs like KDE and etc too.
Never had that issue, your experience may vary based on your hardware and software. I use Arch, sway (wayland), AMDGPU, multiple monitors with mixed refresh rates, everything works great.
NixOS with Gnome Wayland, a 4K 60hz TV, a 144hz WQHD and a 60Hz 1080p Monitor
it would often happen that one Screen would just freeze. my Web Browsers would just crash, especially if i was opening a Video.
and the Gnome-Shell itself would crash and put me into the Login Screen.
sometimes the whole Computer would crash and become unresponsive and not even alt+ctrl+n would help anymore
i don't really like XOrg, it just always feels inferior to Wayland or even Windows.
which is why i am currently using windows until [the Problems get fixed | i upgrade my PC (to an AMD GPU)]
