In a PGTK build of Emacs running on KDE Wayland (versions are below) the position of a frame and the size of the workarea are wrong. These work correctly in non-PGTK builds. For example, (frame-edges nil 'outer-edges) returns (0 0 752 840), even though the top-left of the frame is not over pixel 0,0. In a call to (frame-monitor-attributes) the geometry and workarea dimensions are the same. The workarea is correctly reported as smaller in non-PGTK builds.
I'd prefer that these be fixed, but if not they ought to be documented in etc/PROBLEMS.
