If PPSSPPQt doesn't work well with wayland, I guess one way to workaround it is to force the xcb platform to rely on the Xwayland But I don't see the point to force the wayland plateform under wayland (unless qt is that broken). Same, is this fixing a real issue ? As I understand, the variable can sometimes takes a vnc platform, so it will be sub-optimal (still a corner case). Hope that it helps.
