This allows the client to work when the OpenGL implementation fails if
EGL_RENDER_BUFFER is passed, printing a warning. This should fix issues
with Nvidia proprietary drivers on Wayland.
NVIDIA still do not implement a complete/working DMABUF implementation
yet advertise support. Best to tell the public to complain to NVIDIA
instead of assuming it's a LG bug or an issue with their system.
filters are now not run if `egl_filterSetup` returns false, as such we
do not need additional `enable` checks in `prepare` or `run` and we can
bypass the filters even earlier if they are not enabled reducing load.
Since this->prepared will never be set to true unless the filter is
enabled, this results in the framebuffer setup being done every frame
for no reason, causing a lot of texture reallocations.
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.
This commit adds check for the extensions that we need and then calls
the functions indirectly through gl_dynprocs.
This should improve compatibility with older versions of OpenGL, as we
now fallback to the ARB extensions if possible, and in the case of
glGenerateMipmap, we can handle the function not existing at all.
The Linux OpenGL ABI does not guarantee that glXSwapIntervalEXT will be
exported statically from any library, and indeed on some systems this
function does not link at load time, e.g. with amdgpu-pro. All other
GLX functions that we use are from GLX 1.0, which is guaranteed to be
exported statically.
This commit solves this issue by using glXGetProcAddressARB to load the
function. Note that only the ARB version of glXGetProcAddress is
guaranteed to exist by the Linux OpenGL ABI, which is why we must use
it.
This prevents attempts to grab the pointer after the guest side warp
finishes if the pointer has left the window in the meantime. On Wayland,
this would result in the pointer moving to the middle of the window when
the confine is created.
Previously, all progress made during sleep is reset, so if the thread keeps
getting interrupted before the sleep finishes, the sleep will never complete.
This saves a lot of GPU power for partial updates. Running testufo with
lanczos downscaling and FSR upscaling consumed over 90 W, but with this
commit, consumed only 75 W.
The translucent white modal background sort of cancels out the dark
background we apply to the overlay, which is undesirable. It should
instead further darken the background.
For consistency, we now use igGetColorU32Col(ImGuiCol_ModalWindowDimBg)
to draw the overlay background, to avoid hardcoding the same colour in
multiple places.
Currently, this is visible through how fast the cursor blinks, with it
blinking faster at higher refresh rates. This commit makes the timing
consistent.
