If a pageflip is pending before cleanup, it's still pending after. This
is used line 1177: drm_connector_cleanup is called and
conn->pageflip_pending is checked afterwards.
Fixes#1297
The compositor acts as a relay between applications using the text-input protocol and input methods using the input-method protocol.
This change implements the basic but useful support for input-method, leaving out grabs as well as popups.
This prevents the idle event to be activated on a destroyed
output.
This also makes the backend responsible for free-ing modes, as it
is the one allocating them and adding them to the list. Note that
the DRM backend (the only one using modes) already frees them.
These can be used by toolkits (currently Qt) to choose a default
cursor theme and size. Note that this isn't a perfect solution:
- Per-seat configuration isn't possible
- It's not possible to set the default image
- Live config reload isn't possible
But it's easy to implement and simple. To fix these remaining
issues a separate protocol would be needed.
This desynchronizes our rendering loop with the vblank cycle.
In case a compositor doesn't swap buffers but schedules a frame,
emitting a frame event immediately enters a busy-loop.
Instead, ask the backend to send a frame when appropriate. On
Wayland we can just register a frame callback on our surface. On
DRM we can do a no-op pageflip.
Fixes#617Fixesswaywm/sway#2748
When we send an output frame event, we should not assume that the
compositor is going to call wlr_output_swap_buffers in response to it.
If the compositor does not swap the buffers, the idle event source still
exists and is executed every time the Wayland event loop becomes idle,
which means we send frame events repeatedly until the buffers are
swapped.
This moves the removal of the idle event source out of
wlr_output_swap_buffers and into wlr_output_send_frame, where it is
guaranteed to be removed.
