How to get back rounded corners in Compiz?

  • 772

In Ubuntu 20.04 GNOME Flashback with Metacity, all windows had nice rounded corners like on the screen below:

When I switched to GNOME Flashback with Compiz, non-CSD windows (eg. Firefox or Synaptic) still have those rounded corners, but CSD windows (the ones used by default GNOME applications, like Nautilus) have lost them and now are sharp rectangles:

Is there any way to bring the rounded corners back?

  1. Short answer - No.

    The main problem here is that Compiz does not support _GTK_FRAME_EXTENTS atom. GTK uses it to know if window manager knows how to handle client shadow.

    I think Ubuntu still have patch that makes all GTK windows transparent... So you might be able to adjust .solid-csd CSS to get rounded corners in your theme.

    Real fix is to add needed support to Compiz. You can try to use this:

    It is not merged because it is not ready! Use at your own risk!
