Hot corner ripple animation is still blue in Ubuntu/Ambiance

[Nathanel Titane]

Enabling hot-corners using dconf-editor under 'org.gnome.shell enable-hot-corner' as true, the colour of the ripple is still blue (Adwaita default scheme) since the compiled shell theme still uses the specified asset resource:///org/gnome/shell/theme/corner-ripple-ltr.png - this is also valid for the rtl asset.

I have solved the issue by appending an override to match the current ubuntu.css overrides as follows:

.ripple-box {
  border-radius: 0px 0px 64px 0px !important;
  background: #e95420 !important;
  width:64px !important;
  height:64px !important;
}

.ripple-box:rtl {
  border-radius: 0px 0px 0px 64px !important;
  background: #e95420 !important;
  width:64px !important;
  height:64px !important;
}

I think the GDM login screen texture was intentional for Ubuntu 17.10.

Please file separate bugs for separate issues. I count 3 separate issues here (the ripple, the login avatar alignment, the login texture).

[Nathanel Titane (nathanel.titane)]

Thanks for your response Jeremy.

I filed all three issues in a same report since all three refer to the same styling file (ubuntu.css) under the gnome-shell themes folder.

If it's a must I'll separate the report later on.

Thanks a lot for those bug reports and proposed fix!

On the purple effect, I would be more in favor to use a similar asset than upstream one, just changing the color.

This is what we did for the svg (and generate them at package build time), I'm happy with copyuing the fixed png if you have time to work on them?

[Nathanel Titane (nathanel.titane)]

Hi Didier,

May I ask why you would favour png assets over a css solution, given the already evident nature of the ubuntu.css override file?

Why not streamline?

[Didier Roche-Tolomelli (didrocks)]

Hey Nathanel, sure!

We are trying to follow what upstream applies as much as possible. They are using a png file there, so I think either working with them to change for css rules or having their png file into a csv is what makes more sense in case they change in the future how they are applying transformations to it.
