It seems to be happening because of this set of events all happening
in the span of a single transaction:
1. You kill a tiled window that is the only window in a workplace.
2. Sway will destroy the workspace but not yet the container - this
makes `con->pending.workspace` NULL.
3. Cursor glyphs get recomputed causing sway to recompute if the cursor
is on a container edge.
4. That computation causes an access to the NULL workspace. Crash.
This became necessary after the removal of the wlr_output_damage object.
Before, the wlr_output_damage destroy signal fired disabling the output,
then after the handle_destroy function would be called.
Fix this to prevent hitting an assert.
Instead of doing this roundabout thing where we get the surface from the
view, let's instead get it from the `wlr_surface_state` that we already
track in `handle_commit`. This makes the NULL state impossible which is
what the old `get_geometry` is checking for and generally cleans
things up a little bit.
Also don't check if the geometry x/y changed, those will always
be 0 for xwayland.
Across a wayland compositor, there are multiple shells: It can be
a toplevel, or a layer_shell, or even something more meta like a drag
icon or highlight indicators when dragging windows around.
This object lets us store values that represent these modes of operation
and keep track of what object is being represented.
Any windows that have never had a title set visually behave closer to
that of an empty title, but are unformattable, as the code bails out
early on a NULL title.
Support the new dwtp (disable while trackpointing) option introduced in
libinput 1.21, allowing users to control whether the trackpoint (like
those in Thinkpads, but not only) should be disabled while using the
keyboard/touchpad.
See: https://gitlab.freedesktop.org/libinput/libinput/-/issues/731
Remove the incorrect attempt to block focus changes when an input grab
is present and replace it with the same logic used for layer_shell-based
screen lockers: restore the focus after changing it.
This fixes a use-after-free of seat->workspace if outputs are destroyed
while a screen lock is enabled.
When removing outputs, it is possible to end up in a situation where
none of the session lock client's surfaces have keyboard focus,
resulting in it not receiving keyboard events. Track the focused
surface and update it as needed on surface destroy.
Sway focuses the inactive child when focusing split containers. However,
there is currently no way to focus the parent container itself by mouse.
A user must use the keyboard to do so.
This commit maintains the current behavior, but makes it such that a
second click on the split container titlebar (i.e., after its children
are visible) focuses the split container itself.
