Track unexpected loss of an admitted fallback independently from normal
stop and UUID revocation. Terminate once both primary and fallback
sessions have disappeared, regardless of notification order.
Make shutdown terminal so concurrent disconnect handling cannot replace
it with restart or running state.
Display server and overlay teardown can still call app_invalidateWindow,
which signals the frame event; the Wayland presentation module does so
when it unregisters its graph. Freeing the event beforehand asserted in
lgSignalEvent while closing the client.
The render thread freed the overlays as soon as it exited, while the
main thread could still be dispatching display server input callbacks
that iterate them. Free the overlays in lg_shutdown instead, once the
render thread has been joined and the display server has shut down.
The overlays now outlive the renderer, so overlayFreeImage must not
call into it; renderer deinitialization has already destroyed all
textures along with the context.
evdev_stop was never called, and calling it revealed unsafe teardown:
the device list was freed before the thread was joined, a zero epoll
descriptor was mistaken for a valid one, and the device loops walked
past the end of the array through a sentinel that does not exist.
Join the thread in evdev_stop and defer the rest to the new evdev_free.
The display server grab hooks route into evdev until its event thread
is joined, so the device state must stay valid until the display
server has been freed; evdev_free then restores the hooks and releases
the state.
Report expected and current protocol versions through the transport
interface and expose session-independent recovery operations.
Offer recovery from the version mismatch popup, publish requests through
the reserved IVSHMEM channel, and select the validated SPICE fallback.
Register SPICE connection and component options in the SPICE transport.
Move generic input and clipboard settings out of the SPICE namespace,
while retaining migration aliases for existing configurations.
Keep PureSpice and usbredir build requirements private to the transport,
and remove obsolete SPICE configuration state from the client core.
Track primary and fallback video with source-specific generations, and
publish a source only after its first frame or software surface is
ready.
Route SPICE surfaces and cursors through the generic render queue. Keep
the current image across handoffs, and switch input only after the new
source has been presented.
Move fallback activation to its worker so display callbacks cannot
block or deadlock the render path.
Treat autoCapture as keyboard ownership while the pointer is inside the
guest viewport. Predict the next local position for both absolute and
relative motion, then release the keyboard before the pointer crosses
an edge.
Keep capture, focus, and deferred evdev transitions consistent while
retaining the latest local position as the prediction baseline.
X11's legacy guest-position synchronization warps the host cursor to
delayed guest updates. With absolute input this feeds old positions back
through cooked motion and pulls the cursor away from window edges.
Skip display-server guest synchronization when the active input is
absolute. Relative input and explicit uncapture alignment are unchanged.
Rework audio provider and backend lifecycles so playback and capture
callbacks quiesce without blocking real-time threads. Move activation,
teardown, controls, retries, and diagnostics onto bounded workers.
Harden USB audio cadence, feedback, and capture recovery.
Preserve source clocks through recording and pace packets from the
device clock. Bound queues, waits, conversion buffers, and packet sizes.
Make PipeWire and PulseAudio stream control thread-safe and recoverable.
Correct latency clock domains, coalesce rate updates, preserve recent
capture under overload, and keep logging outside real-time callbacks.
Add a composite UAC2 microphone function with its own clock so
recording and playback can use independent sample rates.
Packetize asynchronous capture through usbredir, follow the host
capture clock, and preserve the newest frames across stalls.
Reconfigure active recording without another permission prompt and
fix lost PipeWire capture wakeups.
Treat a negative provider-controlled playback ring as a timeline
discontinuity rather than carrying its underrun debt.
Rebase to the normal low-water target and reset feedback correction so
guest stalls resume at low latency instead of discarding audio for
seconds.
Sample the playback ring graph at its original 40 Hz rate so its
1,200 entries continue to represent 30 seconds of history.
Keep packet processing and asynchronous USB feedback at full rate.
Advertise an asynchronous UAC2 OUT endpoint with explicit feedback so
Windows paces USB audio from the host playback clock.
Drive feedback from measured backend consumption plus the existing
buffer phase controller. Preserve the local and backend resampler paths
for providers without active feedback.
Keep audio diagnostics in the correct clock domains, report ring and
backend latency separately, and avoid hot-path feedback wakeups.
