You seem to have either selected these symbols from the toolbar/menu 
that appears in math mode, or held down the Alt key while typing these 
symbols, thereby producing large brackets or separators.

Since large brackets and separators are rendered using characters in TeX 
fonts, the set of bracket sizes which TeXmacs can render is very 
restricted, and even a subscript or superscript can push a pair of 
brackets to the next size available.  Therefore, I suggest retyping them 
as normal symbols (by pressing the vertical bar key once or twice, as 
appropriate), as I usually type them.

It is sometimes useful to produce large forms of these symbols, but they 
need to be in matched pairs.  To produce one of these symbols as a large 
left bracket, either press Alt-L before pressing the symbol's key, or 
select it from the menu which drops down from the "(" toolbar button; 
for a large right bracket, press Alt-R or use the ")" menu, and for a 
large separator, press Alt-M or use the "|" menu.  Large brackets in a 
properly matched pair will resize themselves to the height of the text 
between them, and a large separator will resize itself to the height of 
the innermost bracket pair containing it.  Improperly matched large 
bracket pairs, and large separators used outside large bracket pairs, 
will resize themselves to the height of all text in the equation, 
producing ugly results as in the image you have posted.
