Created attachment 153626 [details] GTK screenshots STEPS TO REPRODUCE Freshly installed system (arch, vanilla kernel, plasma, hybrid graphics intel+nvidia, only nvidia proprietary installed) OBSERVED RESULT (only on X11) - this notification appears in system tray on every login: 'Software Renderer In Use' (setting rendering backend explicitly to OpenGL does not seem to work) - no shadows, transparency, blur on any apps - GTK apps are showing bugged shadow (black square around context menus) - Lock screen has black background (ui elements shown and working) regardless of selected wallpaper EXPECTED RESULT Above list of things to be working. These do work and render correctly under wayland.
