(For me this is specifically on Fedora, and I always switch back to X11 from Wayland.)
(For me this is specifically on Fedora, and I always switch back to X11 from Wayland.)
The only problem I have is with JetBrains IDEs, which seem to have shaky support. They're usable (meaning you can code), but the experience is so wonky that I basically consider they don't support Wayland.
The reason I switched from i3/x11 is that we've got some 27" 5k screens at work that are basically useless at 100%, and Sway handles different scaling settings flawlessly (except for IntelliJ, which seems lost).
As per Windows placement, Firefox won't restore windows on original positions supposedly because of Wayland, somebody please correct me if I'm wrong.
When I only use a scaling factor of 1 on all the screens, it's usable enough, although it still feels sluggish.
I run two different distributions myself, I know a bunch o people on even more different distributions, set of configuration and based on empirical analysis I can assure you that no one has problem with windows placement.
Out of the box I used have more problem with X11 (tearing and font rendering being the most annoyingly common ones) than I have with Wayland.
