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.
It's not just him, but for something else. HiDPI, Ubuntu 24.04, try OnlyOffice or VMWare Workstation. Both don't scale well. I assume other applications also don't scale well. Had to use X. And the scaling isn't even fractional, it's 2x.
It's not just him.
I've had issues with windows popping up on the wrong display and also their scaling.
Works without issue on X11; and I don't even know where to start looking on Wayland.
