Repeated panel updates rebuilt unchanged controls and SVG artwork, cloned composition data, and kept unused workspace icon resources. This reuses controls when their layout stays the same, bounds the SVG cache, removes temporary layout allocations, and releases icon resources when apps close or the workspace style changes.
Rapidly closing a modal could also leave a native surface behind when its asynchronous creation finished after the close. Late openings now get destroyed when their owner is gone. Ferese uses the published `ferese-v0.1.2` Iced/libcosmic fixes so a temporary software buffer/viewport size mismatch retries the frame instead of crashing.
Two runs per version of the same workspace/overview/reload workload measured **26% fewer allocated bytes and 23% fewer allocation calls**. A separate 1,800-cycle notification/modal stress run retained about **40 MiB less shell memory**, including shared-buffer retention falling from 28.2 MiB to 272 KiB. These are measured workload results, not an overall desktop speedup claim.
Validation:
- 1,350 workspace tests passed, including GPU Settings text rendering (50 optional tests ignored); formatting and Clippy passed.
- Native continuous/island panel tests passed rapid notification resizing, modal cancellation, and live material/input-region changes.
- A Wayland lifetime trace confirmed all 280 created modal surfaces were destroyed; longer DHAT traces and Intel GPU memory measurements were checked separately.
- All installation binaries rebuilt and the installation bundle passed inventory and checksum verification.
* Integrate panel composition, adaptive sizing, and overflow
* Add instance editing controls to panel settings
* Add panel group editing and measured composition preview
* Reorganize panel settings and add drag-and-drop item editing
* Simplify panel settings and place inspectors beside the editor
* Refine Panel & Shell settings, previews, and panel rendering
* Organize settings navigation and modernize packaged panel config
* Support top and bottom panels and refine shell surfaces
Add edge-aware settings, previews, popup placement, notifications, margins, and corner rendering. Preserve translucency in notification and dialog controls, and tighten spacing around the clock and display-mode icon.
* Add workspace styles and fix Settings text rendering
* Make panel allocation independent of measurement order
* Normalize panel item settings and visibility
* Move shell geometry into each panel
* Add independent group surfaces and finalize panel configuration
* Keep panel fit checks and restoration consistent with allocation
* Reject unknown panel item options and namespace metadata
* Reject invalid shell startup configuration and remove old radius fields
* Discover workspace application icons in a background task
* Remove the panel architecture document and improve reference prose
* Let panel media fill available space and improve Settings scrolling
* Preserve panel labels across clipped GPU rendering
* Use matching alpine lake wallpapers for light and dark modes
* Fix panel accessibility and popup lifecycle
Apply Reduce Transparency to panel opacity in the shell, compositor, and
Settings preview. Reject unknown theme tokens before snapshot substitution
and validate the current geometry fields in both consumers.
Dismiss popovers and workspace tooltips after panel layout changes. Handle
bar pointer exits directly and recover workspace hover after reentry without
repeated motion updates. Cover the transitions with regression tests and
update the wallpaper dimensions check for the bundled lake defaults.
* Use tagged Ferese toolkit fixes
* Fix center-only panel spacing and headless text rendering
* Bundle native 4K abstract wallpapers for both appearances
* Dismiss workspace tooltips before captured pointer dispatch
* Verify installed JPEG wallpapers when replacing a release
Use shared corner geometry for shell controls, window clipping, materials and blur masks. Preserve circular pills and controls where appropriate, track contour changes in damage, and use tagged ferese-shape and libcosmic dependencies.
Split ScrollingLayout validation so the per-frame geometry solve only
checks scalars and keeps the full tree validation behind debug_assert,
removing a HashSet build from every frame. Replace the per-region Vec
in decode_regions with a stack array via as_chunks, and skip the window
hit test in PointerMotion when Overview is not presenting, where
visual_scale_for_window returns 1.0 regardless.
Guard sync_window_stacking behind a check that the space already matches
the target order with uniform z_index, avoiding an O(n^2) raise_element
loop on every redraw. Narrow window_under_visual to the space iterator
outside Overview, keeping the collected and sorted candidate list for
the Overview branch where front-to-back order is load-bearing.
Raise rust-version to 1.98 and clear the resulting Clippy findings
across the workspace: let-chain collapses, clamp, and while-let loops.
Add compact branded Settings with safe atomic edits, external config refresh and a draggable sidebar. Reconcile services, update connected displays and input devices, apply live layout policy and window rules, and resolve initial floating placement before tiled insertion. Package the Settings launcher and shared Ferese icon.
