Short description of error
Clear Render Border has no menu item in 3D View
Render Border has no menu item in 2D View
Clear Render Border has no menu item in 2D View
Render border doesn't draw a red rectangle in 2D View. Not sure about this issue though. The red border could indeed disturb. And in 3D view it has the red rectangle.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
No Blend file necessary. Open Blender. Switch to camera view. In 3D View click at menu item Render Border in the View menu. Define a rectangle to render. Press F12. Now try to clear the render border by menu. Mission impossible. Menu item not existent. In 2D View both menu items are missing. But hotkey functionality is there.
