Patch Description Author Forwarded Bugs Origin Last update
debian/reftest_compare_surfaces-Report-how-much-the-images-diffe.patch reftest_compare_surfaces: Report how much the images differ
In unattended/non-interactive/autobuilder environments where the images
are not trivially accessible, this provides a way to distinguish between
totally different rendering and more subtle issues.		 Simon McVittie <smcv@debian.org> yes 2024-08-31
insttests/Revert-build-Drop-the-install-tests-option.patch Revert "build: Drop the install-tests option"
Debian and Ubuntu uses these installed tests as part of their
autopkgtest system

This reverts commit 3121f88265ac61733e257f5335473d6f139f158c.		 Jeremy Bicha <jeremy.bicha@canonical.com> no 2023-01-12
insttests/Revert-testsuite-Remove-leftover-test.in-files.patch Revert "testsuite: Remove leftover test.in files"
This reverts commit b598f21506c31d3913c9705a00eb1e8270e9a810.		 Jeremy Bícha <jeremy.bicha@canonical.com> no 2024-12-06
workarounds/reftests-Allow-minor-differences-to-be-tolerated.patch reftests: Allow minor differences to be tolerated
Based on an earlier patch by Michael Biebl, as used in Debian's GTK 3
packaging, with additional inspiration from librsvg's reftests.

Each .ui or .node reftest can have an accompanying .keyfile file
like this:

[reftest]
tolerated-diff-level=20
tolerated-diff-pixels=1000

If the image differs, but the number of pixels that differ is no more
than tolerated-diff-pixels and the differences are no more than
tolerated-diff-level, then we treat it as a success with warnings, save
the .diff.png for analysis, and use g_test_incomplete() to record the
test-case as "TODO".		 Simon McVittie <smcv@debian.org> yes 2021-02-13
workarounds/Disable-inscription-markup.ui-reftest.patch Disable inscription-markup.ui reftest
It's rendered 1px to the left of where it should be, which is not a
serious problem for practical use of GTK, but is a test failure.		 Simon McVittie <smcv@debian.org> not-needed upstream 2022-08-12
workarounds/tests-Mark-gltexture-as-expected-to-fail-on-big-endian-ma.patch tests: Mark gltexture as expected to fail on big-endian machines Simon McVittie <smcv@debian.org> not-needed 2023-08-22
workarounds/tests-Allow-longer-for-a-dialog-to-open.patch tests: Allow longer for a dialog to open
This hopefully makes the test pass more reliably, especially on riscv64.		 Simon McVittie <smcv@debian.org> invalid debian upstream 2023-08-22
workarounds/nodeparser-Adjust-test-for-pango-1.52.0.patch nodeparser: Adjust test for pango 1.52.0
Adjust test result for changed output resulting from

workarounds/testsuite-skip-color-mix.patch testsuite: skip color-mix

workarounds/scaling-test-Skip-floating-point-pixel-formats-with-Cairo.patch scaling test: Skip floating-point pixel formats with Cairo renderer
If the four chosen pixel values happen to have alpha values that average
to 16/17, GTK will quantize that into 8bpp integer space as
16/17*255 = 240, but Cairo/Pixman does its quantization differently and
gets 16/17*256 = 241.		 Simon McVittie <smcv@debian.org> yes upstream 2024-09-03
workarounds/nodeparser-Mark-failing-tests-on-s390x.patch nodeparser: Mark failing tests on s390x Alessandro Astone <alessandro.astone@canonical.com> not-needed upstream 2025-08-18
workarounds/testsuite-Skip-vulkan-tests-that-break-lavapipe.patch testsuite: Skip vulkan tests that break lavapipe Alessandro Astone <alessandro.astone@canonical.com> not-needed 2026-02-10
x11-scale/gdk-x11-check-surface-scale-on-input-region-opaque-region.patch gdk/x11: check surface scale on input region, opaque region/rect
Since in x11 backend the input region, opaque region and opaque rect are
related to scale, it is necessary to track whether the scale is
different so these regions can be updated without changing the logical
size.		 Yao Wei <medicalwei@gmail.com> yes upstream 2025-12-19
x11-scale/gdk-x11-update-correct-shadow-size-according-to-window-si.patch gdk/x11: update correct shadow size according to window size change
Because update_shadow_size is not updated since the logical size of
shadow is not changed, the shadow is glitched out.

This makes sure that the shadow size is recalculated when the scale
is changed.		 "Yao Wei (魏銘廷)" <yao.wei@canonical.com> yes upstream 2025-10-03
x11-scale/gdk-x11-update-cursor-size-on-the-extent-after-scale-chan.patch gdk/x11: update cursor size on the extent after scale change
This will update the cursor size when the scale is changed.
When gnome-shell under Xorg is started in 2x, scaling the UI to
1x the cursor size is correctly scaled to 1x, but it does not
work the other way round.		 "Yao Wei (魏銘廷)" <yao.wei@canonical.com> yes upstream 2025-10-03
testsuite-Skip-gestures-if-running-with-no-seat.patch testsuite: Skip gestures if running with no seat
Like 8912a6eb757c39a6801358331fa81f8f52ebad8a		 Alessandro Astone <alessandro.astone@canonical.com> yes 2026-03-05
