upstream_59b38d97_backends-libinput-Fix-dangling-InputDevices-on-shutdown.patch backends/libinput: Fix dangling InputDevices on shutdown
The current logic assumes that when

m_thread.quit();
m_thread.wait();

runs, the Connection will emit the deviceRemoved() signal for every
available input device and the InputRedirection will perform cleanup.

Unfortunately, it is not quite the case. There are two relevant
connections:

connect(m_connection, &LibInput::Connection::deviceRemoved,
this, &InputBackend::deviceRemoved, Qt::DirectConnection);

in LibinputBackend::LibinputBackend(), and

connect(inputBackend.get(), &InputBackend::deviceRemoved, this, &InputRedirection::removeInputDevice);

in InputRedirection::addInputBackend().

The one in the LibinputBackend constructor works as expected, but the
one in the InputRedirection effectively becomes queued because the
current thread is the connection thread.

This can lead to InputRedirection::devices() including dangling pointers.

There are two ways to fix the issue:

* make the connection in InputRedirection direct
* or somehow make sure that the LibinputBackend emits the
deviceRemoved() signal on the correct thread

The problem with the first approach is that it breaks encapsulation and
it's just not a good fix, the API should remain intuitive without hidden
footguns.

So this patch aims to fix the thread on which the
LibinputBackend::deviceRemoved() signal gets emitted.

upstream_056cf1ce_activation-restore-code-updating-layers-of-fullscreen-windows.patch activation: restore code updating layers of fullscreen windows

It was removed because there's similar code in Window::setActive, but the code
in Window::setActive only updates the main window of the window itself, while
we actually need to update the layers of all fullscreen windows on all screens.
