This is due to a known failure: state/focus1.ui passes in a desktop
session but fails in a minimal autopkgtest VM. Treating one test as
flaky seems better than treating all tests as flaky.
Commit 359df028be changed the
code to send GDK_SCROLL_SMOOTH with deltas instead of
GDK_SCROLL_(UP|DOWN|LEFT|RIGHT).
Windows defines deltas inversed for vertical direction
(positive values mean the wheel was turned forward)
but not for horizontal direction
(positive values mean the wheel was turned towards the right).
This commit fixes behavior as both axes were inverted previously.
Commit 359df028be changed the
code to send GDK_SCROLL_SMOOTH with deltas instead of
GDK_SCROLL_(UP|DOWN|LEFT|RIGHT). Change it again, to send
both the GDK_SCROLL_SMOOTH and the GDK_SCROLL_(UP|DOWN|LEFT|RIGHT)
event separately (with the discrete event marked as emulated),
as this is what other backends (such as wayland) do.
Fixes terminal emulator misbehaviour as outlined in https://gitlab.gnome.org/GNOME/gtk/issues/1316, which was introduced in 49b17e6c. The original commit cleared preedit text by setting it to an empty string, which still counted as existing preedit. The fix sets preedit string to null, which is correctly understood as not present.
For building the introspection dumper program on Visual Studio, leave out
the G_LOG_DOMAIN as g-ir-scanner does not like it when it constructs the
compiler command line for Visual Studio.
Also ensure that we are looking for the freshly-built libraries by looking
for the .lib's from the output directories of the Visual Studio project files.
Simplify the styling of sidebar separators by not setting their borders
and margins rather than trying to drop it afterward, which was actually
not working anyway.
Make the selector less greedy to not remove the background on
non-titlebar headerbars contained in non-headerbar titlebars and only to
the ones contained in headerbar titlebars. This avoid issues in some
applications.
Also make dropping the background more agressive to actually remove it.
