Title bar error

[ManuelReifs]

The theme does not fill the title bar when tiling in Cinnamon and in Mate it occurs when opening new windows, the errors occur in all window managers except metacity. A white corner is shown.

oh, that's interesting. The source image has rounded corners, so that's why it happens. It should be fixed by reworking the tiled style. I'll let you know when that is addressed.
