xdg-shell protocol says:
All active operations (e.g., move, resize) are canceled and all
attributes (e.g. title, state, stacking, ...) are discarded for an
xdg_toplevel surface when it is unmapped.
So, when a xdg-toplevel is unmapped (not minimized), the corresponding
foreign handler should be destroyed to reset attributes.
Fixes a bug that `zwlr_foreign_toplevel_handle_v1::output_enter` is not
sent when a xwayland surface is re-mapped (e.g. opening Slack desktop
app when it's running in background).
Using the output damage_ring for early out will break VRR in
direct scanout mode. The reason being that the damage_ring
will be completely ignored in that mode so we need to check
`output->pending_commit_damage` instead. This matches with
what wlroots has been doing since [0] and it was missed in
the initial port to wlroots 0.18.x.
However, that would then break the magnifier which only adds
its damage to the damage ring. After some discussion with
the wlroots devs we came up with a solution that should work
for both, wlroots 0.18.0 and when [1] is backported to 0.18.1.
Note that even with this PR, VRR in direct scanout mode is
broken in 0.18.0 from the wlroots side and will be fixed once
[1] is backported to the 0.18 branch and 0.18.1 is released.
Fixes: #2078

Chromium sends 2 commits before the commit with a buffer attached. We
were just checking `wlr_box_empty(&view->pending)` to handle the cases
where an initially maximized/fullscreen client is windowed, but that
check was also returning true on the 2nd commit from Chromium, resulting
in an error message: "view has empty geometry, not centering".
71451173 validates the xdg-activation token more strictly by verifying
the source surface attached to the token. That improves the security by
preventing arbitrary focus-stealing.
However, not all clients attach a right source surface to the token or
use the received token for activation. For example, when a notification
client requests thunderbird to activate its window, thunderbird doesn't
use the token passed by the notification client and instead use their own
token, thus the activation is rejected as the surface attached to the
token is not focused.
We will add options to configure the policy for activation requests or
implement urgency hint in some way in the future and reland the source
surface verification.
Contrary to the raw tablet events, the cursor events transform
the coordinates based on a mapped output orientation.
Otherwise those events are the same.
I intended to fix this quite some time ago but didn't get around to it.
I don't think there's any good reason why we need to un-fullscreen a
view when its output is disconnected. We can handle it the same as a
maximized view, and move it to a new output (remaining fullscreen) or,
if all outputs are disconnected, just leave it as-is.
This is helpful for a media-center use-case, where you have just one
view (e.g. Kodi) fullscreen all the time, but the TV might appear to be
disconnected if you switch it to a different source.
Tested with a couple different scenarios:
1. Single output disconnected and re-connected: view stayed fullscreen.
2. Secondary output disconnected: view stayed fullscreen but moved to
the primary output, and the layer-shell panel on that output was
hidden as expected. When the secondary output was re-connected, the
view was moved back (still fullscreen) and the panel on the primary
appeared again.
Fixes: #864
wlr_popup->current.geometry.{x,y} are usually zero on initial commit, so
xdg-popups were always unconstrained against the output which contains
the top-left of the parent toplevel.
This commit changes xdg-popups to be unconstrained against the output
which contains the top-left of preliminary popup geometry designated by
xdg-positioner given as an argument of "get_popup" or "reposition"
requests.
With wlroots 0.18, layer-shell's new_surface event is emitted on
zwlr_layer_shell_v1.get_layer_surface request rather than the first
commit. This change layer-shell clients like fuzzel to flicker on launch
because labwc was sending a configure event with fullscreen geometry due
to the absence of geometry hints on get_layer_surface requests.
This commit removes the code that updates the usable area from
new_surface handler, preventing unintended configure events with
fullscreen geometry.
This implementation is nearly identical to Sway's, except that
it also reloads the configuration, to spur on reloading the
server-side decorations.
v2: Fix style.
v3: Add a reset to the magnifier.
v4: Oops, restructure reset handler a bit.
v5: Commit the magnifier reset immediately, before freeing the
lost allocator and renderer.
v6: Also check for failed render pass, which may return NULL.
v7: Add a second NULL test, just in case.
The initial configure event is now sent explicitly by labwc rather
than by wlroots. We need to move the maximize/fullscreen logic to
the initial commit handling accordingly.
Updates #1956, fixes#1994, replaces #1995.
Adds following settings:
<placement>
<policy>cascade</policy>
<cascadeOffset x="40" y="30" />
</placement>
"Cascade" policy places a new window at the center of the screen like
"center" policy, but possibly shifts its position to bottom-right so the
new window doesn't cover existing windows.
The algorithm is copied from KWin's implementation:
df9f8f8346/src/placement.cpp (L589)
Also added some helper functions to manipulate `wlr_box`.
