border-radius for themes preview

[luigifab]

From mate-appearance-properties theme tab.
Here are screenshots from Fedora Rawhide with Mate 1.26:

As we can see, Traditional and Yaru themes have window border-radius like BlueMenta theme.
But for BlueMenta there are no problems (ok, there is a white background color instead of a transparent background).
How did you that for BlueMenta?

I think it depends on the version of the metacity.xml.

[rave@mother mate-themes]$ ls desktop-themes/BlueMenta/metacity-1/ | grep metacity
metacity-theme-1.xml
metacity-theme-2.xml
metacity-theme-3.xml
[rave@mother mate-themes]$ ls desktop-themes/TraditionalOk/metacity-1/ | grep metacity
metacity-theme-1.xml
[rave@mother mate-themes]$ ls desktop-themes/YaruOk/metacity-1/ | grep metacity
metacity-theme-1.xml

Menta themes support version 2/3.

Good, I found the culprit:

mate-themes/desktop-themes/YaruOk/metacity-1/metacity-theme-1.xml

Line 203 in 4f32d8e

<rectangle color="shade/#86abd9/0.55" filled="false" x="0" y="0" width="width - 1" height="((title_height + 6) `max` (top_height - 2))"/>

But for now I didn't found a solution.

I can see this too. Looks like the Yaru themes inherited it from the Traditonal themes upon which they are based

Maybe the bug is even partially inside blue menta too. Use a image zoom and youll see that thr background gets expanded over the border to the edges.

But white on normal background has indeed much less contrast than blue.
The double border at the edges gets cropped on metacity-/marco once you activate the theme due to the rounded border definition in metacitys xml file.
Its solution would be to a) partially rewrite Yaru and Traditional ok xml file providing image assets if necessary and patching the preview mechanism .

There is now something strange with Mate 1.28 on Fedora, icon + close/maximize/minimze buttons are oversized:

Mate 1.26 with Debian Testing:
