Summary:
The last_active_client is set when an AbstractClient gets activated. For
the X11 case the last_active_client was getting reset to nullptr when
the last_active_client gets destroyed. But for the ShellClient that did
not yet happen. This could result in a crash.
This change addresses the problem and adds a test case which triggered
the crash. The condition of the crash are difficult to generate though -
it took me about an hour to write the test for the crash.
1. Wayland client must be active
2. Explicit focus to null (no active client)
3. destroy Wayland window
4. X11 client which sets focus on itself without interaction with window
manager
Test Plan: test case no longer crashes

KWin cannot handle the layering correctly when a Wayland window is active
and there is a fullscreen X11 window. This test tries to simulate the
situation, but it does not show it.
Nevertheless it's a good test, so let's add it.
CCBUG: 375759
A new test class for KWinBindings added which is intended to group the

Summary:
KWin already used C++14 constructs in a conditional way. This doesn't
make much sense today, it's better to just require C++14.
For KWin only gcc and clang are currently compilers of relevance. Gcc
supports C++14 since version 5 and defaults to C++14 since 6.1 [1].
Clang supports C++14 since version 3.4 [2].
An overview of compiler support in various distributions:
* Debian stable (stretch): gcc 6.3, clang 3.8
* Debian oldstable (jessie): 4.9, clang 3.5
* Ubuntu 17.04: gcc 6.1, clang 3.8
* Ubuntu 16.04: gcc 5.3, clang 3.8
* openSUSE Tumbleweed: gcc 7.1, clang 4.0
* openSUSE Leap 42.3: gcc ?, clang ? [3]
* FreeBSD: clang >= 34 in ports
* Slackware 14.2: gcc 5.3
This overview shows that every distro out there has at least one
supported compiler which can still compile KWin with this change.
[1] https://gcc.gnu.org/projects/cxx-status.html#cxx14

Summary:
The quick tile shortcuts have a feature of moving the window to the next
screen if one presses the same shortcut again.
E.g. if a window is quick tiled to the left on the right most screen,
quick tile again to left should move it to the left screen and quick tile
right. Thus it swaps the borders.
This wasn't handled correctly, especially not for modes like top and
bottom. If a window is quick tiled to the top an impossible mode was
generated: Left | Right. Doesn't make sense.
This change fixes the mode swapping and extends our quick tile testing
to cover the situation.

Summary:
On Wayland aurorae was creating a lot of stress for the system and
basically turning the system unusable in a short time. This was due to
a recursion starting to create OpenGL contexts. The window created a
decoration (aurorae) which created a QQuickWindow. For that KWin creates
an internal window which in turn triggers the creation of a window
decoration and so on and on.
By simply setting the render QQuickWindow as frameless we can prevent
this recursion.
Test Plan: Tested on Wayland and X11. On Wayland the recursion is gone.

Summary:
Weird NVIDIA behavior fixup part 2. Now that we do no longer freeze when
NVIDIA decides to create an OpenGL error on startup
(aefb5f4dd9), we experience a new issue.
KWin is terminating (no idea why, [1]) and at the same time the OpenGL freeze
protection thread is still running. So far we did not terminate the
thread on shutdown and thus we hit an abort in Qt.
This change ensures that we properly terminate the thread on shutdown.
[1] My current theory is that games terminate KWin, common pattern of
bug reports is "steam".

This change implements a missing TODO to generate the restricted move
area for windows with struts (aka panel) on Wayland.
Reviewers: #kwin, #plasma
Subscribers: plasma-devel
Tags: #plasma
Differential Revision: https://phabricator.kde.org/D6611
Summary:
By allowing panels between screens in 5.8 to have a strut we created a
"regression" in KWin. KWin always was wrong, just we didn't notice as
neither Plasma nor previously Kicker set a strut on panels between shared
screen edges.
The strut is created from the edge of the overall screen setup. This
means a panel on the left edge of a screen on the right has the strut
starting from the left screen. KWin uses the strut to restrict the move
resize area: a window decoration is not allowed to go below a strut. Thus
it becomes impossible to move the window from the right to the left
screen.
This change tries to solve this problem by only restricting the move area
on the screen the window with the strut is on. E.g. if the window is on
the right screen, the left screen is not affected. Thus it's possible
again to move a window from one screen to the other as the added test
case shows.
Unfortunately there are still corner cases where this won't work
correctly. If the window is on both screens this won't work. It is also a
rather heavy change for KWin and thus it's targeted for master and not
for the 5.10 or the 5.8 branch. If we notice that the patch works well
and doesn't create further issues, it should be considered for
backporting.

The test introduced with 962a2e39ee is
meant to be used with the breeze widget style as that one triggered the
crashy code. Given the test coverage build.kde.org does not run with the
breeze widget style, so enforce this through manual loading.
Summary:
This is a regression due to changes in Breeze to support Qt 5.8+ behavior
change. KWin's own QPA operates like < Qt 5.7 and breeze was programmed
against that. Due to that it can happen now that Breeze hits code paths
in which KWin does not have a surface.
To trigger one only needed to open the user actions menu twice.
This change adds a test case which simulates the problem and fixes all
crashes happening in the code path.
Most likely shadows are now broken for KWin's own windows, this change is
only to prevent the crash and thus is for 5.10 branch, while shadow
fixing will go to master branch.

Summary:
There is a regression in WindowBasedEdge::soStopApproaching. Due to
only operate when the edge activates for pointer it is possible that
the cursor polling stays active. Explaining the situation:
1. Activate switch desktop when moving window
2. Start moving a window
3. Move mouse into the approach geometry
-> doStartApproaching activates as we are moving a window
4. stop moving window
-> doStopApproaching early exits as the position does not activate for
pointer any more - we are not moving a window
-> cursor polling is still connected and whenever mouse enters edge
approaching is started
The analysis shows that the check whether activates for pointer is wrong
in the case of stop approaching. If the edge started to approach, we also
need to stop approaching.
This change addresses the problem by turning the check into whether the
connection for cursor position update is set.
This is the third bug fix to the X11 screen edge handling after
introducing touch screen edges. This needs more manual testing by
everybody in the Plasma team who is still using X11.

The PresentWindows effect does not hide the window to close the selected
window. Instead it moves it outside the visible area. As this is a
"special" KWin window it is on top of the stacking order and needs to be
ignored in the slideback effect.
Instead of doing a special casing for this window the effect is changed
to ignore windows outside the visible area in general. Windows outside
the visible area just don't make sense to block the slideback effect.

The GL_CONTEXT_LOST flag is not reset when calling glGetError. This of

until it returns GL_NO_ERROR, if all error flags are to be reset."
(see https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glGetError.xhtml)
As KWin calls checkGLError from init call it can result in a freeze of
KWin. This is a regression reported multiple times since the release of
5.10.3 which enabled GLX_NV_robustness_video_memory_purge extension.

Introduce a method Workspace::markXStackingOrderAsDirty
Summary:
This method replaces the calls x_stacking_dirty = true in the code base
allowing for further refactoring of that functionality.
Remove roundtrip to XServer from Workspace::xStackingOrder
The method xStackingOrder is only used during a Compositor paint pass.
If the stacking order had changed, the method updated the stacking order
from X by performing a sync XQueryTree. With other words we had a round
trip to the X server directly in the paint pass.
This change rearchitectures this area by making better use of xcb. When
we notice that the stacking order changed and an XQueryTree is needed,
we directly send out the request. When xStackingOrder is finally called,
which normally happens a few milliseconds later, the reply is retreived.
In the worst case it still blocks, but in most cases the roundtrip is
gone.
If the stacking order changed again before accessing xStackingOrder the
running request is cancelled and a new request is issued. So whenever we
get into xStackingOrder it will have the current state.
The updating of the xStackingOrder is moved into a dedicated method and
xStackingOrder invokes it through a const_cast instead of operating on
mutable variables.

Summary:
The current way to specify the OpenGL context attributes does no longer
scale as can be seen in D6344. There are too many different context
attribute sets and with every addition we grow lots of copied code. The
chances to introduce errors in that code which is difficult to debug are
very high. As can be seen in the glx backend which defines major 1,
minor 2, but it should be major 2, minor 1.
This change reworks this code by creating a builder class which contains
only an abstract definition of what needs to be in the attributes.
E.g. the version, whether it's robust and so on.
Now we can just have a list of possible attributes in a well described
way:
auto builder;
builder.setVersion(3, 1);
builder.setRobust(true);
All possible builders are added to a list and operated on in a for loop
which tries to creat a context. Once it succeeded it breaks the list.
In addition a debug statement is added which prints out the set of
options which went into the context.
So far this is only done for EGL, GLX can follow once D6344 is merged.
