Is there an issue with Wayland for your setup? I run Gnome + Wayland on Fedora, with two monitors with different sizes and different refresh rates - eerything seems to run pretty fine, including gaming?
Not OP but the last time I tried Wayland was about a year ago (also on Fedora) and I had similar issues using multiple monitors with different refresh rates, ended up switching to x11 which resolved it (using an nvidia card with nonfree drivers if that matters). But it seems I'll have to give Wayland another try if they've addressed it since then, I hadn't been keeping up with it.
We're in 2024Q3, things have improved. Nvidia helped out. (X)Wayland/KDE/Qt/GNOME bugs were fixed.
Apart from that, use X11 as long as you wish!
I'm just glad we can finally improve the open source desktop-environment infrastructure to match those of Windows and macOS: we've been stuck for too long.
Indeed. Security (all apps get all keypresses and hard to implement correct behaving lock screens) and multi-monitor with factional scaling per monitor; those were the things that apparently were to super-duper hard to fix in X11.
Maybe a years or two until Wayland gets to full feature parity (except for features Wayland specifically does not have like network support and drawing window borders etc.)
In those same two year I expect all app I use to be running native on Wayland as well. (IntelliJ being the main app I'm waiting for and they are making progress)
