Shared contexts allow us to share textures and vertex buffers between
contexts (windows) this allows us to reduce memory in popups and alike.
To fully make use of this requires some follow up work in
ManagedTextureNode for FrameSVG, but we should sitll get some OOTB.
If shared contexts are not supported this fails gracefully - though we
are relying on shared contexts within kwin for a release without issue.
It also should fix WebGL inside WebViews.
BUG: 448299
Given that the wayland protocol does not have window positions a recent
change to Qt development branch avoids having a mismatch of positions
and tells client code the window is at the topleft of the screen. This
fixes multiple bugs.
Unfortunately this breaks a few usages within plasma where a
side-channel sends that absolute positional information over a bespoke
protocol. Currently we proxy this all through QWindow geometry where the
new Qt behaviour will throw is askew.
Whilst our longterm plans are to find future options away from the
plasmashell protocol we may as well have our Qt6
build work given the patch is trivial and harmless.
It also allows for potential backporting if our software is
already secured against issues. Hence the cherry-pick.
I cross-compiling for the recently released Arm Morello boards and the
QtQml debugger is not yet compatible with CHERI-enabled architectures so
I had to build QtQml with -no-qml-debug.
ShellCorona is created before KDBusService which registers the name.
This causes a problem as we register global shortcuts before plasmashell
--replace has kiled the old application, which in turn deregisters
everything.
We want everything before KDBusService to be as light as possible.
Moving ShellCorona construction is not trivial as some argument parsing
uses that.
BUG: 408310
The two ways of disabling session management have the same impact on the
session being saved, but there is one behavioural side-effect that
turned out to be less ideal.
By disabling completely we don't follow the session manager telling the
application to quit. That's not something needed with the systemd boot,
but for the legacy boot effectively we were just closing applications by
ripping the X connection away from under them.
Some applications are bad at handling this and this led to a bunch of
crashes or dangling processes at logout.
This reverts commit 9be7dedb87.
CCBUG: 424408
ShellCorona is a messy class doing mulitple functions.
This patch splits out all telemetry code into a new class, meaning it's
easier to extend. Code remains the same.
Qt 5.15 introduces a new syntax for connections.
Framework code can't port away due to having to support Qt5.12 which
does not include the new syntax.
This filters out the category.
We should remove this once we depend on Qt5.15 in frameworks.

Summary:
As discussed the env variables are no longer exported. Thus Qt
applications follow the default qpa platform they are compiled with and
thus still function if they are packaged with a Qt without QtWayland.
Plasma's internal processes pick the qpa platform depending on the
session type as well as our flatpak apps.
KRunner and Plasmashell are adjusted to not leak the env variable they
set for themselves.

that plasmashell and krunner are wayland. Launched kwrite from both plasma

Summary:
This is a preparation step to unset QT_QPA_PLATFORM from the wayland
startup session script. Setting QT_QPA_PLATFORM breaks 3rd-party Qt
software which does not bundle QtWayland. Most prominent example is
the Qt installer itself (see
https://bugreports.qt.io/browse/QTBUG-60222).
On the other hand our Plasma workspace applications need to be forced to
Wayland on a Wayland system. So we have a conflict between we want to
set QT_QPA_PLATFORM and we don't want to set QT_QPA_PLATFORM.
This change adds new API to KWorkspace to address this problem. The new
method adjusts the QT_QPA_PLATFORM based on the XDG_SESSION_TYPE
enviornment variable. It is completely opt-in. Meaning applications need
to explicitly add the call prior to creating the QGuiApplication and if
the user specifies either QT_QPA_PLATFORM env variable or any of the
-platform command line argument variants, the platform detection is
skipped.
The change also adjusts all plasma-workspace applications which should
use Wayland on Wayland to use the new API. The startup script on the
other hand still sets QT_QPA_PLATFORM. We also have applications outside
of plasma-workspace which needs this detection. Examples are:
* powerdevil
* systemsettings
* kinfocenter
Once this change is merged those applications can be adjusted by linking
against PW::KWorkspace and afterwards QT_QPA_PLATFORM can be unset from
startplasmacompositor.

Summary:
Setting a window icon is surprisingly costly and a decent chunk of
startup time. The shell doesn't need one. The only place I could
find where this icon is visible is in the KSysguard process list :).
Some people may be reminded of this rejected request:
https://git.reviewboard.kde.org/r/128484/
But that's Plasma::Dialog in plasma-framework, which (currently)
still sets an icon. This is about the shell.

Summary:
The directory containing the main application (read through argv[0]) is
by default added to the list of paths containing libraries.
This causes various methods to iterate through all entries of the plasmashell
install location, usually /usr/bin.
By explicitly removing the path, those unnecessary lookups can be avoided,
resulting in around 100ms quicker startup on a system with 4000 entries in
/usr/bin.
Test Plan:
Ran plasmashell with and without this fix, no changes except for a slightly
quicker startup and much less strace noise.
