--- Comment #5 from Vlad Zahorodnii <vlad.zahorod...@kde.org> --- @Ethan not sure if you're the right person to speak or should I go downstream, but SDL's initialization sequence of initially fullscreen windows is not optimal with kwin. with kwin_wayland, the ideal startup sequence looks as follows: -> create xdg_toplevel -> set app_id, min/max size -> call set_maximized or set_fullscreen if the window has to be displayed maximize or fullscreen, respectively -> create xdg_toplevel_decoration if needed and set the preferred mode -> wl_surface_commit() <- kwin responds with a configure event -> start painting \o/ In other words, kwin_wayland really wants to have as much as possible initialization happen before the first surface commit. See also https://bugs.chromium.org/p/chromium/issues/detail?id=1268308 But it seems like SDL can issue several set_fullscreen requests and commit the surface multiple times with no buffer attached until the window is finally mapped. -- You are receiving this mail because: You are watching all bug changes.
