When a child window of a fullscreen client is mapped, the fullscreen is
disabled, and if the previously fullscreen client is floating the child
window is rendered below it and cannot be seen, causing confusion,
though it is still focused and interactable.
Fix this by putting children of fullscreen clients in LyrFS instead of
LyrFloat, and by returning before the unset_fullscreen code is called
when they are mapped.
focusstack() now lets you switch focus from a fullscreen client to its
child windows, otherwise if you switch focus from the child window to
the fullscreen client you could not focus the child window again and the
fullscreen client would stay unresponsive.
Child clients are not reparented to LyrFloat after leaving fullscreen,
so you could spawn a child window, focus back the fullscreen client,
unfullscreen it, and the child window would still be drawn above other
floating clients. Avoid dealing with this edge case to keep the line
count low.
These cases can be tested by pressing Ctrl+o in applications with an
open file dialog.
Revert 3213088 because the linked bug can no longer be reproduced with
wlroots 0.17, and update client_get_parent() so it doesn't segfault with
XWayland surfaces. This also allows reusing the p variable in the next
commit.
These don't do anything because wlr_scene_node_reparent() is immediately
called again by setfloating() through setmon(). They are also a source
of confusion because if you change the wlr_scene_node_reparent() call in
applyrules() it takes a while to understand why it doesn't work.
For wine clients often configurex11() is called before mapnotify() and
therefore c->mon is NULL. configurex11 just returns early in that case,
letting these clients stay in the wrong size. For example only the top
left part of winecfg and wine uninstaller is drawn, or confirmation
dialogs like when closing wine notepad are too big. Fix this by
configuring their surfaces like before 88d386b.
The compositor must respond to the client requesting a change to the decoration
mode, it does not matter if the compositor chooses a different mode.
This reverts commit 9071ce6c84.
previously it worked because we checked in every commit the layer
in a353eee2ca and
b100b446b8
we changed the way it's handled and now if the layer surface does not change
the layer we don't it either. meaning that if it was created in the bottom
layer and did not change the layer the popups would show behind xdg clients
