Собственно, сабж. Ранее в ноябре 2023-его года авторы PCSX2 назвали Wayland забагованным и отключили его поддержку: https://www.phoronix.com/news/PCSX2-Disables-Wayland-Default
Теперь же в феврале 2025-го года авторы PCSX2 внезапно увидели, что Wayland уже готов и включили его обратно: https://www.phoronix.com/news/PCSX2-Wayland-Default
This comes a year and a half after they resorted to disabling Wayland support after finding it «super broken/buggy in basically every scenario. KDE isn't too buggy, GNOME is a complete disaster.» But since then much of the Wayland support has improved across desktops and throughout the Linux software stack.
In the latest testing of PCSX2 on Wayland by its developers, they did uncover a new upstream Qt toolkit bug. That Qt bug is around a Wayland rendering issue when using native windows on GNOME/Weston.
Great seeing the maturity of Wayland software support continue.
