My experience has been somewhat different. I've had a linux server for a long time so I'm not new to the OS but my main computer which I use for development and gaming and everything else has always been Windows. I recently added a dual-boot Ubuntu for some performance-heavy development where the better docker integration made sense for me to use.
I had to try three window managers until I was able to use fractional scaling in such a way that my main 4K 32" screen shows 150% and my secondary screen shows a sharp image because Gnome cannot do fractional scaling only on one screen and for some reason 100% resulted in a blurry image.
The window manager crashed multiple times when I tried to unlock it.
Whenever I woke up my screen the whole system froze, apparently because of the USB hub in the monitor which registered. So far the only solution has been to disconnect the USB hub.
Fan control doesn't work properly because the chipset isn't supported.
I see rendering issues with window decorations all the time.
That's just after two weeks. I can't remember the last time my windows froze or crashed or had display errors. Whenever I'm in the console or do IO heavy stuff I feel right at home but as a desktop OS it's still inferior to me. I don't have fewer problems on Linux, just different ones.
I stopped recommending Ubuntu years ago. I've daily driven fedora, pop_os! and a few arch derivatives with few or zero issues for years, switching it up when I get new hardware just out of curiosity.

This is my new daily life with Windows 11. I've got a client that requires some software that can't run under Linux (even with wine) and picked up a fairly spendy new laptop with windows on it. Not a day has gone by in the last three months I haven't regretted being forced to use it. Hangs and glitches every day for a minute or two, occasionally to the point that I give up and force restart it.

Does your Gnome install use Xorg? If yes, than it supports this. Xrandr settings are per screen. That is independent from the Window manager.
