  UI: Allow alpha on playhead The playhead was drawn in front with full opacity, covering everything that is below it. This creates issues in the dopesheet and graph editor because artists cannot see the keys when the playhead covers them. The solution is to allow transparency on the playhead. In order for this to look good, I had to change the drawing to be pixel perfect. Otherwise we'd bright spots where the alpha of the different elements doubles up. As a result, the tip (connecting piece between box and stalk) is now drawn as a trapezoid. Only the stalk (the line itself) is drawn transparent. They playhead box is forced to full opacity to keep the clarity of the text. Note that this does not change the default theme to be transparent. IMO that is a different discussion to be had. I just allow the transparency here and make sure it looks good. This solves the issue addressed in #149823 in a different and immediate way.

  GHOST/Wayland: Add watcher for desktop theme change Mainly exists as a demonstration for the previously added D-Bus watcher. This just includes logging for when the system theme changes. Pull Request: https://projects.blender.org/blender/blender/pulls/163356

• Hans Goudey(01 Sept 26)

  GHOST: Add DBUS-based desktop settings watcher (GHOST_SystemDBusUnix) This commit introduces an API for watching desktop setting changes for Linux, built around libdbus. It's designed around the initial use case of reading the system theme (light or dark) and changes to the value (implemented in !161872), but design to be extensible enough to watch other settings too. The watching is done on a background thread, so that Blender doesn't have to poll as part of a busy loop. Instead, callback functions passed to the watcher have flexibility over how they pass the data to Blender, e.g. sending an event.

  GHOST/Wayland: Dynamically load libdbus libdbus is now loaded with dlopen at runtime, like `libwayland`. The new `WITH_GHOST_WAYLAND_DBUS_DYNLOAD` option (default on) toggles this; off keeps direct linking. Headers are still needed at build time. This isn't used yet, but it will be used for cursor themes, and for watching the system theme choice in !161872. This is a tweaked version of !158527.

  Fix #163272: Metal: Allow running Blender without GPU. When no Metal device is detected it will fallback to dummy device.

  Refactor: UI: Activate area filters from hidden regions This adds a more generalized way to operators to activate text buttons in regions; this first tries to activate the text button in the region, and if it fails it tags to rebuild the layout so there is a second chance to the button to become available for activation. This refactors how some operators activate text buttons, most of them assumed the button were visible, and others immediately redrew the region so the buttons can be made available. This instead makes the button activation part of the block layout build. This will affect Preferences, Properties, Space Text and Outliner.

  Fix: Animation playback wrongly reported as playing during pre-callback start_playback() created the animation timer before running the ANIMATION_PLAYBACK_PRE callback and starting sound playback. The `bpy.app.handlers.animation_playback_pre` handlers would see `context.screen.is_animation_playing` as True, where before it was always False during that callback. This rolls back part of the fix in d620e03e752 and takes another approach. That commit moved the creation of the timer to ensure its 'started from' frame was correct. Now the timer is created in the same place as before, and its data is simply adjusted afterwards to store the correct 'playback started from here' frame. This issue was introduced in d620e03e752.

  EEVEE: Add Support for Panoramic Camera View # Implemented - Panoramic camera types: equirectangular, equiangular cubemap face, fisheye equidistant, fisheye equisolid, fisheye lens polynomial, central cylindrical, mirror ball. - Render 6 subviews (fixed 90° FOV each, 5% overscan). - Subview enable/disable masking (PanoramicViewBits) to skip faces not needed for narrow FOV. - Accumulate radial depth for panoramic projections. - Film accumulation per owning face per pixel. # Future tasks ### Turned off for now - Depth of Field - Volume temporal reprojection history state is shared across all 6 subviews instead of per-view, so it's disabled for now. Per-view history would be the real fix. ### Optimizations - Per-face render resolution: scale each cubeface's resolution to its actual angle contribution instead of a fixed size. - Clip each subview's projection matrix to its actual visible FOV instead of always rendering the full 90°. Needs care to clip to exact pixel borders, or reprojection onto the film breaks. - Stencil mask per subview to avoid computing weights. (currently: pixels not owned by a face just copy their existing value and return early). ### Known limitations - Film sampling use nearest-texel only, not a proper filter kernel (a 3x3 or plus-shaped 5-sample kernel would reduce aliasing/banding) - No antialiasing at boundaries. - Screen-space raytracing hits subview boundaries and creates artifacts. Possible fix: overscan parameter and make a blend between the cubefaces. Pull Request: https://projects.blender.org/blender/blender/pulls/159474

  Fix #162650: Failing vulkan texture view tests Vulkan backend used the texture format to perform data conversions, it ignored the format of the view, resulting in incorrect or missing data conversions. This is fixed by using the view format to perform data conversions. These texture view conversions aren't used in Blender, but having all 3 backends providing the same result is a very welcome.

  Outliner: Move object hierarchy to target collection during drag-drop Drag-drop for an object to target collection just moves parent object. For children objects, user need to select hierarchy before dragdrop. To avoid this extra effort, move children objects along with parent to the target collection. New function `find_child_objects_recursive` to iterate/store child objects inside Vector, it's called from `collection_drop_invoke`. Now by default entire hierarchy is moved to target collection. For old behavior of "drag drop just parent object", use `ctrl + shift + LMB drag`. See PR description for video and RCS thread Pull Request: https://projects.blender.org/blender/blender/pulls/156916

  Fix: Motion Path update issues Fix issues reported by the LLM * While we tracked the evaluated range, it was actually reset in the inner loop, rendering it ineffective. The fix is to use a Vector of evaluated ranges that builds up on every loop. * the `stable_result_counter` was not reset when switching to evaluating the range on the other side of the start frame. That is now fixed.

  Fix: Depsgraph: missing relations for collection under excluded ancestor Ensure the right dependency graph relations exist when part of a hierarchy of collections is excluded from the view layer. When a collection is excluded, its children are parented to their closest non-excluded ancestor. Commit 61ed5b3d246d changed the relation builder so that recursion stops at an excluded layer collection when the parent is excluded; the node builder still visits the excluded collection.

  Fix #162884: Node tree interface accessors to prevent crash on nullptr Socket names and descriptions can be set to empty strings, which results in `nullptr` being assigned to the DNA `char *` fields. Using the nullptr directly is not supported in many places (such as UI names for RNA properties) so a lot of boilerplate code is required to check for nullptr everywhere. This issue has come up in the past, but there was nothing to prevent newer uses of name strings to make the same mistakes. To simplify code and make it more robust in the future the relevant name and description strings now have accessor functions `name()` and `description()` for const access, which return a `StringRefNull`, replacing any nullptr with an empty string. The original DNA fields are renamed to `name_` and `description_` to indicate they are considered "private" and should only be accessed directly by internal code that needs write access.

  Fix #163439: playhead text drawing outside indicator in VSE scrub UI Regression introduced in 0b5135ae95 where playhead text was drawn outside the blue indicator box in the VSE/Time Scrubbing region. In `draw_current_frame`, `PlayheadDimensions` was using unclamped coordinates during layout calculation. ### Solution 1. Pre-evaluate `PlayheadDimensions` to obtain the actual box width. 2. Clamp `region_x` so the box and text do not overflow the region bounds when positioned at frame 0/1. 3. Re-evaluate `PlayheadDimensions` with the final clamped `region_x` position so that all rendering stages use identical, synchronized geometry rects.
