octotablet reads pen events from its own queue on winit's Wayland connection and only dispatches what is already there. winit read them from the socket but, finding none of its own events, went back to sleep without AboutToWait, so pen strokes waited until something else woke the loop: they showed up late or only after touching the screen. Until 0.39.3 the app redrew continuously, which hid this; the battery fix there exposed it. Every read from the socket now wakes the app. Idle CPU under a headless Wayland compositor stays at 0.

# winit 0.29.15 for ink-notes
|
|
|
|
Copy of [winit 0.29.15](https://crates.io/crates/winit/0.29.15) (Apache-2.0, see
|
|
`LICENSE`), used through `[patch.crates-io]` in the top-level `Cargo.toml`. Examples, tests and
|
|
docs of the original crate were removed.
|
|
|
|
## Changes
|
|
|
|
- `src/platform_impl/linux/wayland/seat/touch/mod.rs`: on Wayland, winit draws the title bar
|
|
itself (client-side decorations) but only handles the mouse there. Touches on the title bar
|
|
are now passed to the frame like a left click: close, minimize and maximize work with a
|
|
finger, and dragging the title bar moves the window (Issue #36). All changes are marked with
|
|
`ink-notes patch`.
|
|
- `src/platform/wayland.rs`: `ignore_decoration_touches_until` lets ink-notes ignore touches on
|
|
the title bar while the pen is near the screen, so a resting palm does not move the window
|
|
(Issue #39).
|
|
- `src/platform/wayland.rs` and the touch handler: `take_touch_time` returns the compositor
|
|
timestamp of each touch event (Started, Moved, Ended), so ink-notes measures the swipe speed
|
|
for gliding with the real event times and not with the time it got around to handling them
|
|
(Issue #28).
|
|
- `src/platform_impl/linux/wayland/event_loop/mod.rs`: every read from the Wayland socket wakes
|
|
the app (`AboutToWait`), also when the events belong to another queue on the same connection.
|
|
octotablet's pen events live on such a queue and only `dispatch_pending` it, so before, pen
|
|
strokes waited until something else woke the loop (Issue #53).
|
|
- `Cargo.toml`: `[lints.rust] warnings = "allow"`, because a path dependency is not built with
|
|
capped lints like a crates.io dependency.
|
|
|
|
Remove the copy and the `[patch.crates-io]` entry when ink-notes moves to a winit version that
|
|
handles touch on its decorations.
