This change alters the small square dot cursor to a more visible 16x16
cursor for X11. A new option `spice:largeDotCursor` can be set to use an
alternative 32x32 cursor for the vision impaired.
This adds a new `audio:bufferLatency` option which allows the user to
adjust the amount of buffering LG does over the absolute bare minimum. By
default, this is set large enough to absorb typical timing jitter from
Spice. Users may reduce this if they care more about latency than audio
quality.
This adds a new `audio:periodSize` option which defaults to 2048 frames.
For PipeWire, this controls the `PIPEWIRE_LATENCY` value. For PulseAudio,
the controls the target buffer length (`tlength`) value.
This prevents LGMP_ERR_QUEUE_FULL from happening with high polling rate
mice, which is caused by receiving many more mouse events while the
guest cursor warps, triggering more warps.
When using jitRender, or on the first frame of an alert the window
doesn't get resized immediately causing it to cut off the end of the
text.
ImGui needs two passes to calulate the bounding box for automatically
sized windows, this is per it's design and not a bug, see:
https://github.com/ocornut/imgui/issues/2158#issuecomment-434223618
If the guest supports sending us it's UUID and PureSpice has also
reported the guest's UUID, check them to see if the user has
accidentially connected to the wrong spice socket.
The cursorThread prevents the host from going to sleep when the
video feed is disabled as it's subscribed to the cursor queue. Stopping
the cursorThread will unsubscribe from the queue and allow the host
application to disable capture.
Currently, this is visible through how fast the cursor blinks, with it
blinking faster at higher refresh rates. This commit makes the timing
consistent.
imgui really hates it when we update the modifier key state after igNewFrame.
The result is:
void ImGui::ErrorCheckEndFrameSanityChecks(): Assertion
`(key_mod_flags == 0 || g.IO.KeyMods == key_mod_flags) &&
"Mismatching io.KeyCtrl/io.KeyShift/io.KeyAlt/io.KeySuper vs io.KeyMods"'
failed.
Therefore, we buffer the modifier state information and update it in the IO
object right before we call igNewFrame.
This adds a new `earlyInit` call which allows the overlay to register
options before actually being intialized. Also the keybind handling and
state tracking for each overlay has been moved internal to the overlay
itself.
The way things were handled in EGLTexture is not only very hard to
follow, but broken. This change set breaks up EGLTexture into a modular
design making it easier to implement the various versions.
Note that DMABUF is currently broken and needs to be re-implemented.
When requested, JIT render mode will be used if the display server supports it.
Otherwise, a warning is generated instead.
This essentially uses the signalNextFrame logic for imgui, but for everything.
We automatically enable this mode when overlay is on.
Currently, this exposes some damage tracking bugs in the EGL renderer.
