Filter-Menü
The following options (these switch the corresponding options in the UV-Einstellungen menu.) affect the elements that are normally visible in the texture view and only serve informational purposes. The following options can be used to show or hide the respective information.
Texture UV Editor at the top left.
The green/red rulers at the edge of the working area.
The UV axis displayed at the bottom left.
The ruler markings.
If, for example, you hover the live selection cursor over UV elements, these will be highlighted (to show that they can be clicked on and selected). If this bothers you, simply disable this function.
Here you can switch the UV Grid on and off.
