bug#25474: 26.0.50; Buffer content invisible

[Ivor Durham]

Clicking on menu items produces the expected drop-down. Hovering over icons 
produces the expected tooltip. Selecting Help/About produces a blank buffer. 
Selecting Help/GNU launches the browser as expected. So it appears to be only 
the buffer content display that is not working.

Does Emacs respond to input?  For example, if you move the mouse pointer to 
hover above one of the tool-bar buttons and wait for a second, does a tooltip 
pop up describing the button?  And if you click on a menu-bar item, do you see 
a menu drop down?

If the above produce no response, can you see if Emacs is consuming CPU cycles?

Thanks.
