[31c91db0]161 One test is known to fail if
[1e361b35]162 <ulink url="https://gitlab.gnome.org/GNOME/cantarell-fonts">Cantrell fonts</ulink>
[31c91db0]163 are not installed.

165 About a dozen of tests are known to fail with minor (mostly invisible)
166 differences between the render output and the shipped reference image.
167 Issue
168 <command>grep 'not ok' meson-logs/testlog-x11.txt -B3</command>
169 (use <filename>testlog-wayland.txt</filename> if testing in a Wayland
170 session) to list them and the image files showing the render output,
171 the reference output, and the differences. You may take a look at
172 those images to ensure the differences are insignificant.
173
174 Two <literal>headless</literal> tests are known to fail without the
175 external dependency pydbus installed.
[964682d8]176
177 Many tests will fail if <filename>~/.config/gtk-4.0/settings.ini</filename>
178 exists and the gtk-modules line is not commented out.
[31c91db0]179
180 Several other tests may fail for unknown reason.
[964682d8]181
[55844bf]182 On systems with NVIDIA graphics cards, the tests may take significantly
[5d0f39ee]183 longer than the above test time.
[31c91db0]184 <!--
[964682d8]185 On some systems as many as 212 tests may fail (out of over 6100) for
186 unknown reasons.

188 I hope this is gone with LIBGL_ALWAYS_SOFTWARE and -\-no-suite dmabuf.
