v0.4.1

The default look changed. A config that sets only some keys gets the new defaults for the rest: rounding, gaps, shadows, borders, tab strips, animations and blur. docs/config.md lists the keys for the old look. Binds in the built-in config don't reach a config with its own binds; the new ones are listed below.

just docker hardware passes on an RTX 3060 Ti, with simulated vsync. None of this has run on a real display, and no touchpad has been tried.

Added

• Gestures. A gestures config for swipe, pinch and hold. Three fingers horizontally switch workspaces, tracking 1:1 and settling with the fingers' velocity.
• Overview. The overview action (SUPER + Tab, or three fingers vertically) lays out live windows, with workspace thumbnails to click or drag onto. overview-scrub-30-follow-open is 5.5% late on the RTX, so the overview's pacing steps are reported but not gated yet.
• Layout holds. A tiling change lands in one frame, or within 100 ms if a client doesn't answer. Input is never held.
• Zoom. SUPER + =, SUPER + -, SUPER + BackSpace, SUPER + CTRL + scroll, SUPER + two-finger pinch. Captures show the unzoomed screen.
• Drag preview and snapping. Edges give a half, corners a quarter, the top edge the full usable area. drag_preview.enabled: false turns off both.
• Reduced motion. animations.reduced_motion, with an IPC query and event.
• Frame pacing. lys-wm -frame-trace, the lys-wm-pace tool and just pace.
• SUPER + Space opens lys-shell launcher in the built-in config.

Changed

• A default look per renderer: everything on a GPU, no blur on CPU drivers, also no shadow or animated workspace switch on software. Any key you set wins.
• A frame slower than half a refresh can now take up to a full refresh, instead of missing every vblank.
• Genie no longer re-renders an unchanged window every frame.
• Spring maths and Xcursor come from lys-lib.

v0.4.0

Nothing here has run on a real GPU or an HDR display yet: the renderers were tested on llvmpipe and lavapipe, and HDR with KMS fakes and virtio.

Added

• Minimize. xdg_toplevel.set_minimized, X clients, foreign toplevel handles and the minimize and restore actions all work, with a genie animation (windows_minimize) and a minimized field and event over IPC. Tiled windows come back beside the focused window, not in their old spot.
• Blur for clients. ext_background_effect_v1, and blur behind popups.
• Glass. decoration.blur gains tint, saturation, brightness, contrast, grain, refraction, specular and mica; window rules gain blur_look and mica. All off by default. A closing window keeps its frost.
• Screen shaders. outputs[].shader post-processes an output in a subset of GLSL ES 1.00, on all three renderers; docs/shaders.md has examples. Lock screens and captures see the image unshaded, and the software renderer is too slow for real use.
• HDR. outputs[].hdr drives an output with PQ in BT.2020, off by default, with wp_color_manager_v1. An HDR output costs about 66 MB at 4K, and screen shaders stay off on it.
• Esc for dropdowns. lys_escape_v1 gives a dropdown one bare Esc while another window has the keyboard. That Esc doesn't reach the window.

Fixed

• A layer dropping its keyboard focus now gives it back.
