# Parked for later milestones

Issues found while building, with the milestone that owns them.

## M7

- vkcube showed a black window for about half a second at startup. First-time dmabuf imports now run on a worker thread, which was the likeliest cause. Needs a re-test on bare metal, with a spans log if it persists.
- Direct scanout setup on a fullscreen switch (framebuffer creation for client buffers) still runs on the main thread inside `render_frame`. Measure its cost before moving it.
- SCHED_RR and the realtime queue priority both need CAP_SYS_NICE, which monolith does not have when started normally.

## After M6

- wlr-foreign-toplevel minimize requests are ignored, since tags have no minimized state.
- X11 windows do not raise in X stacking order on focus, which only matters for overlapping floating X windows.
- Dialogs from xdg toplevels with a parent float, as do X11 dialogs, transients and fixed-size windows. Portal file choosers arrive with no parent and still tile.
- Some programs open an X connection just to probe, vkcube among them, which starts Xwayland lazily even though they draw through Wayland.
