Description:
Using Lo 7.1.0.1 (x64) on Win 10 (64 bit)
build b585d7d90ab863bf29b2d110c174c0c2a98f3ee4 

The "View > User Interface..." dialog offers a total of 7 UI interfaces. But we cannot select three of them because the three buttons at the bottom of the dialog cannot be clicked at all.

(The tree buttons are: Apply to all, Apply to writer, Close)

The reason is simple: The dialog contains explanation text for each UI variant (located on the right side of the dialog, just above the buttons). In some UI options, the text is longer, and thus the frame extends to the bottom, and overlaps the buttons. We can see the buttons through the frame, but cannot them.

(Workaround: A thing strip of the buttons is exposed at bottom. If we click there, the buttons work.)

In some options, the frame shrinks vertically because of less explanatory text, which means the buttons are exposed fully. Here we have no problems in clicking these buttons.

To sum up, the problem exists with the following options:
#1. "Standard toolbar"
#2 "Tabbed" and 
#7 "Sidebar" 

Steps to Reproduce:
1. Select View> User interface... menu.
2. Look at the dialog box.
3. Select options 1,2 or 7. Try to click on the buttons
